Abstract
The invention discloses a bendable surgical scissors for laparoscope. The bendable surgical scissors for the laparoscope comprises a pull rod which penetrates a scissor head portion and is connected to a scissor handle; a head portion of the pull rod is connected with a straight joint of the scissor head portion; the straight joint is connected with a tension spring piece; the outer portion of the pull roll is sleeved with a guide sleeve; the head portion of the guide sleeve is sleeved with a front sleeve; pressure cap is sleeved on the outside of the front sleeve; the guide sleeve and the front sleeve are pressed together through the pressure cap; a knot is sleeved outside the guide sleeve and the front sleeve; the rear portion of the knot is connected with a bayonet lock; the push rod stretches and rotates so as to pass through the straight joint and drive the tension spring piece to bend and stretch; the head portion of the tension spring piece is sleeved with a connecting sleeve, the head portion of which is provided with a clip positioning joint; the clip positioning joint is connected with a curved scissor head through a connecting piece. The bendable surgical scissors for the laparoscope have the advantages of easily completing surgery that can not be completed or is hard to complete, reducing damage to the body of a patient and improving success rate of the surgery.
Description
Technical field
The invention belongs to technical field of medical instruments, relate to a kind of bendable surgical scissors of peritoneoscope.
Background technology
Bendable surgical scissors, in operation process can in the body of patient the torso portion of the bending operating scissors of different angles, thus get around some organs and directly arrive the position that will perform the operation, human abdomen's perforate number of times can be reduced, thus reduce the infringement of human body and operation can be made more convenient.Operating scissors is originally all straight, because people's intracorporeal organ is more and operating scissors is straight, can run into some organs during operation hinders operating scissors to arrive operative site, so need repeatedly to punch human abdomen to reach operation object, like this to the infringement of human body is comparatively large and operating process is also extremely inconvenient.Compared with former operating scissors can scissor bending after avoid organ and reduce infringement or do not damage, then control scissors bit wipe out focus by controlling front hand grip and back handle after arrival lesions position.
Summary of the invention
The object of the present invention is to provide a kind of bendable surgical scissors of peritoneoscope, it is all straight for solving existing operating scissors, because people's intracorporeal organ is more and operating scissors is straight, can run into some organs during operation hinders operating scissors to arrive operative site, so need repeatedly to punch human abdomen to reach operation object, like this to the problem that infringement is comparatively large and operating process is also extremely inconvenient of human body.
The technical solution adopted in the present invention comprises pull bar, pull bar runs through shears head and is connected to scissors handle, rod head connects the straight joint of shears head, straight joint connects stretch bending shell fragment, the oriented guide pin bushing of pull bar outer cover, guide cover head cover has protheca, protheca overcoat has pressure cap, pressure cap will force together to guide pin bushing and protheca, also overlap to guide pin bushing and protheca outside and have knob, knob rear portion connects runner, runner rear portion connects bayonet lock, can prevent runner from rotating by depresses detent, when unclamping bayonet lock, runner is free to rotate, pass through rotating wheel, drive knob, knob drives pull bar to stretch and rotates, pull bar is flexible and rotate thus drive stretch bending shell fragment bend and stretch by straight joint, stretch bending shell fragment head cover has adapter sleeve, adapter sleeve head is provided with intermediate plate landing nipple, intermediate plate landing nipple is by brace connecting bending scissors bit, stretch bending shell fragment is bending and when stretching, thus make curved scissors cutter head also carry out rotation bending, to stretch into particular orientation in human body, be convenient to needs of performing the operation, handle is provided with resilient handle pin, appropriateness folding when handle pin can make handle hold, facilitate scissors grip.
Further, described pull bar is metal pull bar, can be provided with electronic thermo-head cylinder lever connecting rod, heated by electronic thermo-head to pull bar at handle place, and when preventing from performing the operation, metal bending scissors bit is supercool.
The invention has the beneficial effects as follows can scissor, can complete the operation that some cannot complete or be difficult to more easily, reduce the infringement of many patient bodies, improves the success rate of operation.
Accompanying drawing explanation
Fig. 1 is the shears shank structural representation of bendable surgical scissors of the present invention;
Fig. 2 is the shears head structural representation of bendable surgical scissors of the present invention.
In figure, 1. pull bar, 2. scissors handle, 3. straight joint, 4. stretch bending shell fragment, 5. to guide pin bushing, 6. protheca, 7. pressure cap, 8. knob, 9. runner, 10. bayonet lock, 11. straight joints, 12. stretch bending shell fragments, 13. adapter sleeves, 14. intermediate plate landing nipples, 15. braces, 16. curved scissors cutter heads, 17. handle pins, 18. electronic thermo-heads.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
The present invention is scissor construction figure as depicted in figs. 1 and 2, wherein A line is scissor construction figure cut-off rule, comprise pull bar 1, pull bar 1 runs through shears head and is connected to scissors handle 2, pull bar 1 head connects the straight joint 3 of shears head, straight joint 3 connects stretch bending shell fragment 4, the oriented guide pin bushing 5 of pull bar 1 outer cover, protheca 6 is had to guide pin bushing 5 head cover, protheca 6 overcoat has pressure cap 7, pressure cap 7 will force together to guide pin bushing 5 and protheca 6, also overlap to guide pin bushing 5 and protheca 6 outside and have knob 8, knob 8 rear portion connects runner 9, runner 9 rear portion connects bayonet lock 10, can prevent runner 9 from rotating by depresses detent 10, when unclamping bayonet lock 10, runner 9 is free to rotate, by rotating wheel 9, knob 8 is driven to rotate, knob 8 drives pull bar 1 stretch and rotate, pull bar 1 is flexible and rotate thus drive stretch bending shell fragment 12 bend and stretch by straight joint 11, stretch bending shell fragment 12 head cover has adapter sleeve 13, adapter sleeve 13 head is provided with intermediate plate landing nipple 14, intermediate plate landing nipple 14 is by brace 15 connecting bending scissors bit 16, stretch bending shell fragment 12 is bending and when stretching, thus make curved scissors cutter head 16 also carry out rotation bending, to stretch into particular orientation in human body, be convenient to needs of performing the operation, handle is provided with resilient handle pin 17, appropriateness folding when handle pin 17 can make handle hold, facilitate scissors grip.
