According to the enhanced puncture outfit seal assembly for the laparoscope, the structure is simple, operation is convenient, working is stable and reliable, it can be guaranteed that breakage cannot occur on the basis that gas is not leaked out, the defect that a traditional puncture outfit seal ring is broken after an instrument goes in and out for multiple times in the surgery process is completely overcome, the smoothness of a surgery is guaranteed, harm to a patient is reduced, and the therapeutic efficiency is effectively improved.
Description
Technical field
The present invention relates to a kind of surgical operation medical apparatus and instruments, particularly relate to a kind of reinforced peritoneoscope perforator black box.
Background technology
Peritoneoscope Minimally Invasive Surgery is the invasive methods that a new development is got up, it is an inexorable trend of following operation method development, in laparoscopic surgery, perforator is used for puncturing to human body abdominal wall tissue, carries gas and sets up the passage of operating theater instruments from turnover abdominal cavity, the external world.After setting up pneumoperitoneum, puncture cover uses as the passage during turnover of puncture needle, operating theater instruments, sealing ring in black box then plays the effect that leaking does not appear in the gas ensured in human abdominal cavity, and the mode that sealing ring many employings multi-disc diaphragm seal of traditional perforator black box is superimposed as round shape sealing ring seals, gap can be produced between diaphragm seal and diaphragm seal, cause gas to leak outside and cause intraperitoneal air pressure unstable, operation has some setbacks to such an extent as to the situation being forced to stop of performing the operation, make troubles to doctor, damage to patient.
Summary of the invention
The technical problem to be solved in the present invention is: not good in order to solve existing black box sealing effectiveness, cause gas leak, operation is caused to have some setbacks, injury is brought to patient, add the problem of the cracky that sealing ring thickness fixedly brings, the invention provides a kind of reinforced peritoneoscope perforator black box and solve the problems referred to above.
The technical solution adopted for the present invention to solve the technical problems is: a kind of reinforced peritoneoscope perforator black box, be arranged between puncture needle and puncture cover, comprise sealing upper cover, upper press cover, dome-type sealing ring, lower cover and sealing lower cover, dome-type sealing ring is fixed by upper press cover and lower cover pressing, upper press cover and lower cover are fixed by sealing upper cover and the pressing of sealing lower cover, dome-type sealing ring center is provided with through hole, dome-type sealing ring periphery is extended centring ring, centring ring is provided with some locating holes, the thickness of dome-type sealing ring is from bottom transition to top progressive additive.
Further, comprising locating hole has ten, and ten locating holes are distributed on centring ring.
Further, comprise below gland He above lower cover and be provided with locating dowel, and locating dowel and the suitable realization of locating hole are fixed.
Further, to comprise below upper press cover and locating dowel above lower cover is five, and the corresponding locating hole of the locating dowel of upper and lower is interspersed.
Further, comprise dome-type sealing ring outer and be provided with shirt rim.
The invention has the beneficial effects as follows, structure is simple, easy to operate, working stability is reliable, can ensure that gas leaks on basis not producing, there will not be breakage, evaded traditional perforator sealing ring completely in operation process, there is damaged drawback in apparatus, ensure that the unimpeded of operation after repeatedly passing in and out, alleviate the injury to patient, effectively improve therapeutic efficiency.

Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As Fig. 1, 2, 3, shown in 4, a kind of reinforced peritoneoscope perforator black box of the present invention, be arranged between puncture needle 1 and puncture cover 3, comprise sealing upper cover 21, upper press cover 22, dome-type sealing ring 23, lower cover 24 and sealing lower cover 25, dome-type sealing ring 23 is fixed by upper press cover 22 and lower cover 24 pressing, upper press cover 22 and lower cover 24 are fixed by sealing upper cover 21 and the pressing of sealing lower cover 24, sealing upper cover 21 uses ultrasonic bonding to be connected with sealing lower cover 25, dome-type sealing ring 23 center is provided with through hole 232, dome-type sealing ring 232 periphery is extended centring ring 233, centring ring 233 is provided with some locating holes 231, the thickness of dome-type sealing ring 23 is from bottom transition to top progressive additive, dome-type sealing ring 23 outer is provided with shirt rim 234, locating hole 231 has ten, and ten locating holes 231 are distributed on centring ring 233, locating dowel 221 is provided with below upper press cover 22 He above lower cover 24, and locating dowel 221 and the suitable realization of locating hole 231 are fixed, locating dowel 221 below upper press cover 22 and above lower cover 24 is five, and the corresponding locating hole 231 of the locating dowel 221 of upper and lower is interspersed.
Through hole 232 in the middle of dome-type sealing ring 23, Main Function is for when puncture needle 1 passes in and out with other operating theater instruments, play air seal, stop the effect of gas leak, the upper thickness at the circular position, bottom of dome-type sealing ring 23 is smoothly transitted into bottom for thinning gradually, enhance the bearing capacity of dome-type sealing ring 23, locating hole 231 has 10, and be distributed on the centring ring 233 at edge, locating dowel 221 on upper press cover 22 and lower cover 24 is interspersed, successively through ten locating holes 231, then pressing centring ring 233, dome-type sealing ring 23 is fixed, because dome-type sealing ring 23 has elasticity, when apparatus is through locating hole 231, the position, shirt rim 234 of locating hole 231, can fit with instrument seal, gas can not be leaked, by black box 2, puncture cover 3 connects combination, puncture needle 1 and other operating theater instruments, during turnover puncture cover, can ensure that gas leaks on basis not producing, there will not be breakage, evade traditional perforator sealing ring completely in operation process, damaged drawback is there is in apparatus after repeatedly passing in and out.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content in description, must determine its technical scope according to right.
