Description

Vascular suture pincers under peritoneoscope

Technical field

This utility model relates to a kind of vascular suture pincers, particularly relates to vascular suture pincers under a kind of peritoneoscope；Belong to operation Apparatus.

Background technology

Elastic separating plier is a kind of medical apparatus and instruments conventional in laparoscopic surgery；Generally by vice body, consolidating of being fixed with one therewith Hollow claw beam that fixed clamp handle activity clamp handle, the runner that be located at vice body on and this runner hinged with vice body is connected, it is fixed on this The clamp seat of claw beam front end, be hinged on this clamp seat front end two clamps, respectively with two corresponding two the hinged connecting rods of clamp, The pull bar the most hinged with two connecting rods is constituted, such as: CN201481497U, CN201631309U, CN201719319U, CN201775678U, CN201968766U, CN202179591U, CN202515775U etc..

It is known that sometimes for blood vessel breakage being tied process in operation process, and said structure elastic separating plier Jaw work surface on be not available for hole or the groove that stitching thread passes through.When the blood vessel wall vising breakage with clamp is stopped blooding Time, two clamps will occupy and tie position thus impact ties process to blood vessel breakage；When troublesome poeration, operation Between long.Further, since clamp occupies the position of knotting, therefore typically require and just carry out stitching thread after being unclamped by clamp beating Knot；And the most once unclamping clamp, blood will be spouting from breakage, thus causes perform the operation blurred vision, increase operation Risk.3rd, the clamp handle of current elastic separating plier is not provided with retaining mechanism, and clamp handle of must holding with a firm grip in the moment in sewing process could be protected Card clamp is kept closed；Therefore both hands cannot be used to carry out tying operation, and it is tired to be easily caused surgical staff.

Summary of the invention

For drawbacks described above present in prior art, this utility model aims to provide one and had both been easy to vascular suture operation Process, have again vascular suture pincers under the peritoneoscope of preferable haemostatic effect.

To achieve these goals, this utility model is by the following technical solutions: it includes that vice body and this vice body are fixing even The fixing clamp handle that the is integrated activity clamp handle hinged with described vice body, the runner being located on vice body are fixed with this runner and are connected Hollow tubular claw beam, it is fixed on the clamp seat of this claw beam front end, is hinged on two clamps of this clamp seat front end, respectively with described Two corresponding two the hinged connecting rods of clamps and the most hinged pull bar of described two connecting rods are constituted, and the other end of this pull bar is with described Activity clamp handle is flexibly connected；Crossed beam trunking or cable-through hole is offered on the jaw work surface of two clamps；Above-mentioned two clamp handles are provided with lock Tight mechanism.

Crossed beam trunking is U-shaped groove-like structure；Described retaining mechanism by the button being articulated in fixing clamp handle, be fixed on this button And the first spring, the bayonet lock being fixed on button between fixing clamp handle, be articulated in fixing clamp handle and carry serrate locking plate, The second spring of being fixed between this locking plate and fixing clamp handle, the card tooth plate being fixed in activity clamp handle are constituted, locking plate has with The draw-in groove that bayonet lock is suitable.

Compared with the prior art, the structure of tradition elastic separating plier, owing to have employed technique scheme, is entered by this utility model The simple transformation of row: add on the jaw work surface of clamp be available for U-shaped that stitching thread passes or the crossed beam trunking of C font or Person is available for the cable-through hole that stitching thread passes；When the blood vessel wall that clamp vises breakage carries out hemostatic suture operation, even if two Clamp occupies and ties position, and sewing needle also can pass from crossed beam trunking or cable-through hole, and thoroughly avoiding traditional operation must be first Elastic separating plier is unclamped and just can carry out sewing up operation；Not only shorten operating time, and can also be prevented effectively from because unclamping elastic separating plier And cause the defect bled profusely.Further, since add retaining mechanism in clamp handle, clamp handle of therefore need not holding with a firm grip i.e. can ensure that Clamp stays closed all the time state, not only improves both hands and carries out sewing up operation, saving muscle power again.

Fig. 3 is clamp assemblies structural representation of the present utility model；

Fig. 4 is enlarged drawing at the B in Fig. 1.

In figure: activity clamp handle the 1, second bearing pin 2, fixing clamp handle 3, the 3rd bearing pin 4, button the 5, first spring 6, bayonet lock 7, the Two springs 8, clamp 9, clamp seat 10, claw beam 11, runner 12, vice body the 13, first bearing pin 14, locking plate 15, card tooth plate 16, jointed shaft 17, crossed beam trunking 18, mounting groove 19, spacer pin 20, stopper slot 21, connecting rod 22, pull bar 23.

Detailed description of the invention

The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings:

As shown in figures 1-4: fixing clamp handle 3 is fixing with vice body 13 to be connected as a single entity, activity clamp handle 1 by the first bearing pin 14 and Vice body 13 carries out hinged, and runner 12 is arranged on vice body 13 by bearing (not shown), the claw beam of hollow tubular 11 with turn The fixing docking of wheel 12, this claw beam is fixedly arranged at the front end with clamp assemblies.This clamp assemblies is docked and front end is with U by fixing with claw beam 11 The clamp seat 10 of font mounting groove 19, two clamps 9 being jointly hinged in mounting groove 19 by jointed shaft 17, respectively with two institutes The pull bar 23 stating corresponding two the hinged connecting rods 22 of clamp 9 the most hinged with described two connecting rods 22 is constituted；The other end of pull bar 23 Through the clamp seat 10 of hollow form and claw beam 11 and activity clamp handle 1 floating connection, the jaw work surface of each clamp 9 offers in The crossed beam trunking 18(of U-shaped or C font can also be cable-through hole).In order to avoid producing relative turning between clamp seat 10 with claw beam 11 Dynamic, the front port of claw beam 11 offers stopper slot 21, fits with stopper slot 21 phase with having in the section of cooperation of claw beam 11 at clamp seat 10 The spacer pin 20 joined.

In order to easy to operate, above-mentioned two clamp handles are provided with retaining mechanism.This retaining mechanism is by by the 3rd bearing pin 4 pivot The first spring 6 of be connected on the button 5 in fixing clamp handle 3, being fixed between this button and fixing clamp handle 3, it is fixed on button 5 Bayonet lock 7, it is articulated in fixing clamp handle 3 and carries serrate locking plate 15 by the second bearing pin 2, be fixed on this locking plate and fixing clamp handle The second spring 8 between 3, the card tooth plate 16 being fixed in activity clamp handle 1 are constituted, and locking plate 15 has the card suitable with bayonet lock 7 Groove (does not indicates in figure).
