Abstract

The utility model relates to a surgical instrument which comprises a hollow handle (1), a puncture tube (2) and an inner core (3). The surgical instrument is characterized in that the hollow handle (1) is connected with one end of the puncture tube (2), the inner core (3) penetrates through the hollow handle (1) and the puncture tube (2), a bent hook is arranged at one end of the inner core (3), and when the other end of the inner core (3) is pushed or pulled from the hollow handle (1), the bent hook of the inner core (3) extends out of or retracts from one end which is provided with an opening of the puncture tube (2). The surgical instrument has the advantages of overcoming defects of the prior art, being safe, providing convenience, and being not prone to damaging tissue in accomplishment of a hook retraction process of puncture.

Description

A kind of operating theater instruments

Technical field

This utility model relates to a kind of operating theater instruments.More specifically, the present invention relates to a kind of operating theater instruments for returning hook net, band or line after the piercing tissue.

Background technology

At present, the operating theater instruments that the surgical operation of selling on the market is used for returning after the piercing tissue hook net, band or line all is terminal design with holes, fixedly is pulled the purpose that thing reduces tissue injury when pulling back simultaneously to reach.There is the three aspects: defective in this design, and the one, the art middle punch is wasted time and energy and is increased the corrective surgery risk; The 2nd, the doctor can not see the traction point and must be pulled thing with doigte " blind wearing " in the part operation, and this incurs loss through delay operation in practice can reach 30 minutes, and this patient to unlimited wound surface is undoubtedly very dangerous; The 3rd, the operator bores a hole may be by sharp cutting tip damage in the fixing operation.

The utility model content

The purpose of this utility model is to overcome deficiency of the prior art, a kind of safe and convenient ground is provided, is difficult for the by mistake surgical operating instrument of finishing the hook process that punctures back of damaged tissue.

A kind of operating theater instruments comprises hollow grip, puncture tube and inner core.

Described hollow grip is connected with an end of puncture tube, described inner core passes hollow grip and puncture tube, one end of this inner core has crooked hook, and at the other end of hollow grip place push-and-pull inner core, the hook of the bending of this inner core has a uncovered end from puncture tube and stretches out or retract.

Further, described hollow grip has retainer, presses the fixedly position of inner core.

Further, described puncture tube is bending or spiral, and described inner core has flexible.

Further, the hook of the bending of described inner core is the terminal bending with inner core, and the interior angle of bending is 75 °～105 °.

Further, the hook of the bending of described inner core has a uncovered end from puncture tube and stretches out 0.1～4mm.

Further, described inner core diameter is 0.05～3mm, and the puncture tube internal diameter is 1.5～3 times of inner core diameter.

The beneficial effects of the utility model are:

(1) adopts the telescopic hook structure, can penetrate smoothly and withdraw from body tissue and do not cause machinery and involve wound with smooth hollow puncture tube.

(2) under can the range estimation condition, puncture reaches and starts flexible inner core behind the target location and stretch out telescopic hook, and the operator can directly will be pulled the thing lodge to gib head, without any obstacle.

(3) wear under the condition blind, the flexible inner core of startup stretched out telescopic hook after puncture reached the target location, and the operator can need not range estimation only will be pulled the thing lodge to gib head with finger touch, substantially not have obstacle.

When (4) gib head can directly adopt the little straight hook design of bending, can better avoid unexpected hook body tissue.

(5) gib head stretches out hollow puncture tube end under the surgical work state, has reduced the damage operator's of sharp hollow puncture tube end probability.

The specific embodiment

Below in conjunction with accompanying drawing, this utility model is further described.

As shown in Figure 1, carry out a kind of operating theater instruments of the present utility model, comprising hollow grip 1, puncture tube 2 and inner core 3.

Described hollow grip 1 is connected with an end of the puncture tube 2 of bending, and puncture tube 2 has a uncovered end and has sharp tip.Described inner core 3 has flexible, pass hollow grip 1 and puncture tube 2, an end of this inner core 3 has crooked hook, at the other end of hollow grip 1 place push-and-pull inner core 3, the hook of the bending of this inner core 3 has a uncovered end from puncture tube 2 and stretches out or retract, and is illustrated in figure 2 as hook and stretches out state.The hook of the bending of described inner core 3 is the terminal bendings with inner core 3, and the interior angle of bending is 75 °～105 °.The hook of the bending of described inner core 3 has a uncovered end from puncture tube 2 and stretches out 0.1～4mm, can ensconce 0.1～2mm in the puncture tube 2 when this crooked hook is retracted fully.Described inner core 3 diameters are 0.05～3mm, and puncture tube 2 internal diameters are 1.5～3 times of inner core 3 diameters.Puncture tube 2 also can be spiral.

Described hollow grip 1 has retainer, presses the fixedly position of inner core 3.As shown in Figure 3, a kind of structure of retainer comprises a plurality of grooves 15 that have on briquetting 11, spring 12, slide bar 13, stop button 14 and the slide bar, and inner core 3 is connected with slide bar 13, presses briquetting 11, slide bar 13 can slide in hollow grip 1 interior front and back, moves forward and backward thereby promote inner core 3.Press stop button 14, the arresting lever of stop button 14 lower ends inserts in the groove 15, stops slide bar 13 to drive inner core 3 and moves.

The hook place diameter of the bending of the inner core 3 of a kind of operating theater instruments that this utility model is concrete is 1mm, angle is 90 ° of angles, part after the complications is long to be 2mm, hollow puncture tube 2 intracavity diameter scopes are 2.5mm, the hook of the bending of inner core 3 is apart from puncture tube least significant end 2mm when stretching out, and the hook of the bending of inner core 3 is taken in puncture tube 2 interior 0.5mm positions fully during retraction.

When the operator adopts this utility model related surgical to perform the operation such as the uterine prolapse sticking patch, press first the hook of the bending of the locked inner core 3 that makes telescopic hook C of stop button 14 and retract puncture tube 2 fully with interior state, after the enforcement puncture reaches the target location, decontroling stop button 14 ejects the hook of the bending of inner core 3, need not under the visual condition, operator's other tissue of sharp puncture tube 2 damage that can need not to worry, and with after fixedly guipure hangs up gib head of target network sheet, with the hook again locked inner core 3 of retracting, then pull back and draw fixed network and bring to body surface and finish the puncture distraction procedure.
