Description

Deep electric knotter

Technical field

The present invention is a deep electric knotter, belongs to medical apparatus and instruments, is specially adapted to the inaccessiable deep of hands surgical ligation.

Background technology

Present operation generally strikes knot with the hand, for fat, otch dark and the operation that is difficult to appear, row organizes ligation very difficult, influences the accuracy and the speed of ligation, especially the laparoscopic surgery ligation is more difficult.Sometimes with enlarging otch or pressing from both sides and finish, increased damage, increased the weight of patient's misery but enlarge otch with silver, titanium; With silver, titanium presss from both sides not only cost height, also makes in the metallic foreign body long-term storage patient body, have come off, volume is big, the shortcoming of electromagnetism ill effect, should not frequently use.Our medical operation electric knotter complex structure in the past can not close in the make and break of push switch button and compress line to the end, and stringing is inaccurate, uses inconvenient.The ligation difficult problem of Minimally Invasive Surgery has caused that domestic and international expert payes attention to, but still unresolved so far.

Summary of the invention

The objective of the invention is to be to overcome above-mentioned the deficiencies in the prior art part and provide a kind of and carry silk thread volume, line feeding bar line sending, knotting back stringing, loose ends freely, be fit to the not damaged deep electric knotter of little otch and laparoscopic surgery.

The objective of the invention is to realize by following measure:

The present invention is by on-off circuit, around the line sending control device, button, spring, tension disc, housing is formed, on-off circuit comprises motor, rechargeable battery, the closed circuit that normally closed switch and Closing Switch constitute, comprise the coil of wire around wire-sending device, defeated line plate and line feeding bar, bobbin is fixed on the motor shaft, on the defeated line plate defeated line hole is arranged, normally closed switch adheres to an end of defeated line plate, the button contact adheres to the Closing Switch on the tension disc, spring extrapolation tension disc, housing comprises shell, shell line lid, the shell extension is inserted with line feeding bar, the line feeding bar end has through wires hole, wire hole, there is button hole the shell side, the charging hole, wire hole has the spring holddown groove in the shell, motor axis hole, the tension disc axis hole, cushion rubber blocks water between motor axis hole and motor.

The present invention compared with prior art has following advantage:

(1) only need a wire twister that carries the coil of wire, through thin bar finish line sending, cover line, to organizing ligation, saved deep ligation in the past at every turn with clamp line, line sending, go to clamp the process of carrying the toe-in bundle again, improved ligation speed.

(2) this wire twister only needs thin bar to enter the ligation position, and the motor stringing is easy to control in ligation place stringing power without gear, and is more simple in structure, durable than medical operation electric knotter in the past, is more suitable for the ligation of aperture safety.

(3) tension force meets the ligation requirement during wire twister loose ends, stretch injury ligation tissue neither, untwisting not again.

(4) without metal clip, expense is low, tissue stimulation is little with silk thread, can frequently use for this wire twister.

(5) waterproof sealing is arranged, be convenient to sterilization, be fit to medical.

(6) this deep electric knotter, when principal character is to press shift knob make and break to close, make tension disc compress line at last again being pressed into, make fixedly stringing of line that the through wires hole of line feeding bar end draws, having improved the ligation reliability, is that in the past medical operation electric knotter can not be accomplished.

The specific embodiment

With reference to accompanying drawing, motor 1 adheres on the shell 2, cover blocks water and wears motor axis hole 4 on the shell behind the cushion rubber 3 on the motor shaft, the cementation coil of wire 5 on the motor shaft, facing on the defeated line plate 6 at the coil of wire 5 places defeated line hole 7 is arranged, defeated line plate one end cementation has normally closed switch 8, tension disc 9 one end live conductor plate axles 10 are fixed in shell tension disc axis hole 11 (partial cutaway figure A in the Figure of description) and go up rotatable, cementation has Closing Switch 12 on the tension disc, spring 13 tension disc of on holddown groove 14, extrapolating, button 15 is inboard facing to Closing Switch 12, the button hole 16 of the button outside on shell stretches out outside the shell, and shell extension 17 is inserted with line feeding bar 18, and line feeding bar is a stainless steel tube, the shell end has entrance hole 26, and head end has through wires hole 19, wire hole 20.Wired lid 21 on the shell 2 (partial cutaway figure C in the Figure of description).Adhere to socket 23 on the shell socket aperture 22 (partial cutaway figure D in the Figure of description) and connect the positive and negative electrode of rechargeable battery 24.Line feeding bar can be made the polytype that different length has difference in functionalitys such as cover line, trimming.On the coil of wire 5, line end has through wires hole 19, wire hole 20 to draw by hole 7, shell wire hole 25 (partial cutaway figure C in the Figure of description), line feeding bar 18 with wire-wound.Use line end to draw as the distribution pneumascos laparoscopic by hole 7, entrance hole 26, wire hole 20.The positive pole of motor, the negative pole of motor, battery, normally closed switch and Closing Switch constitute closed circuit.

Before the use, the line lid 21 on the shell 2 is opened in wire twister charging, sterilization, and the line of the coil of wire 7 is pulled out through the hole, pass along defeated line plate 6, shell wire hole 25, again through through wires hole 19 penetrate, wire hole 20 draws the end of a thread.Clamp tissue place is directly entangled in wire hole 20 line sendings of line feeding bar 18 during ligation, the light button 15 of pressing in knotting back is connected Closing Switch 12, motor 1 rotates, the coil of wire 5 rotates stringing, line feeding bar 18 push-down handle toe-ins are pushed the tissue of ligation to, the weight button 15 again, it is motionless that tension disc 9 is pushed down line, make normally closed running jointly close 8 disconnections simultaneously, the motor stall pushes away line and backguy power opposite sign but equal magnitude this moment, autonomous stringing power is grasped as required, release button is also outwards pulled out line feeding bar, and loose ends tension force is very little, can not damage the ligation tissue because of the ligature tractive.Beat second, third knot successively by above-mentioned steps, finish a ligation.Trimming after the ligation.Also can deliver to the pipe sex organization place that pincers separate needs ligation to line, elastic separating plier presss from both sides the outlet ligation in passing.

By zoopery and clinic trial, respond well.
