Description

Novel surgical forceps convenient for distance adjustment

Technical Field

The utility model belongs to the technical field of surgical instruments technique and specifically relates to a novel operation tweezers of convenient roll adjustment.

Background

The surgical forceps are one of the most common surgical tools, the surgical forceps are used for clamping articles or tissues, the existing surgical forceps are mostly fixed together at the lower ends of two forceps arms, the forceps arms are pinched inwards in two directions during use, so that the pinching heads at the front ends clamp the articles to be clamped, the forceps arms at two sides cannot be automatically locked when the surgical forceps are used for clamping the articles, two fingers are required to pinch the forceps arms at two sides all the time, the clamping force is unstable, the clamped articles are easy to loosen and slide, and the use is very inconvenient.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the technical defects and provide a novel surgical forceps with convenient distance adjustment. The forceps arms at two sides can be close to or far away from each other by rotating the adjusting knob, so that the forceps arms are clamped or loosened, the forceps arms can be automatically locked at any time when being clamped by the screw in a screw connection mode, articles can be stably clamped, and the forceps are simple and convenient to use.

The utility model provides a technical scheme that technical problem adopted does: a novel surgical forceps convenient for distance adjustment comprises a handle, forceps arms, forceps heads, an adjusting knob, screws and guide rods, wherein the handle is a shell with a hollow inner part and an opening front end, the upper end and the lower end of the inner wall of two sides of the handle are fixedly connected with the guide rods with square cross sections, the middle parts of the inner walls of two sides of the handle are respectively provided with a rotating groove, the screws are rotatably inserted into the rotating grooves of two sides, the middle parts of the upper shell and the lower shell of the handle are respectively provided with a rotating window, the adjusting knob is arranged in the rotating window and fixedly connected to the middle part of the screw, the screw directions of the screws on two sides of the adjusting knob are opposite, the forceps heads are fixedly connected to the front ends of the forceps arms, the width of the forceps heads extending towards the inner sides of the forceps arms is equal to the width of the rotating windows, the lower sides of the forceps arms are provided with threaded holes matched with the screws, two guide holes matched with the guide rods, the upper and lower guide holes of the forceps arms are movably sleeved on the guide rod, and the compression spring is sleeved on the guide rod between the forceps arms at two sides.

The outer wall of the lower end of the handle is fixedly connected with a hanging rod in a threaded mode, and a hanging ring is movably inserted into the hanging rod in a inserted mode. The surgical forceps can be conveniently hung and placed by the hanging ring.

The utility model discloses the beneficial effect who has is: the utility model has the advantages of reasonable design, can make the tweezers arm of both sides be close to simultaneously or keep away from through rotating adjust knob to make the tweezers arm press from both sides tightly or loosen, can lock automatically at any time when tweezers arm and screw rod spiro union can make tweezers arm centre gripping, centre gripping article are stable, convenience simple to use.

Detailed Description

The present invention will be described in detail below with reference to fig. 1 and 2.

As shown in figures 1 and 2, the utility model comprises a handle 1, forceps arms 2, forceps heads 3, adjusting knobs 7, screws 8 and guide rods 9, wherein the handle 1 is a shell with an inner hollow front end opening, the upper and lower ends of the inner walls of the two sides of the handle 1 are fixedly connected with the guide rods 9 with square cross sections, the upper and lower guide rods 9 with square cross sections can ensure that the forceps arms 2 on the guide rods 9 can only be straightly close to or far away from but can not rotate, the middle parts of the inner walls of the two sides of the handle 1 are respectively provided with a rotating groove, the screws 8 are rotatably inserted in the rotating grooves at the two sides, the middle parts of the upper and lower shells of the handle 1 are respectively provided with a rotating window 6, the adjusting knobs 7 are arranged in the rotating windows 6, the adjusting knobs 7 are fixedly connected to the middle parts of the screws 8, the screw directions of the screws 8 at the two sides of the adjusting knobs 7 are opposite, the adjusting knobs 7 can ensure that the forceps, when the forceps arms 2 are close to each other, the screw holes 12 in the forceps arms 2 are in threaded connection with the screw rods 8 and can be automatically locked at any time, so that the forceps arms 2 are clamped and automatically locked without manual continuous force application, the forceps heads 3 are fixedly connected to the front ends of the forceps arms 2, the width of the forceps heads 3 extending towards the inner sides of the forceps arms 2 is equal to the width of the rotating window 6, the screw holes 12 matched with the screw rods 8 are formed in the lower sides of the forceps arms 2, two guide holes 10 matched with the guide rods 9 are symmetrically formed in the forceps arms 2 on the two sides of the screw holes 12, the two forceps arms 2 are symmetrically in threaded connection with the screw rods 8 on the two sides of the adjusting knob 7, the upper guide holes 10 and the lower guide holes 10 of the forceps arms 2 are movably sleeved on the guide rods 9, and compression springs 11 are sleeved. Adjusting knob 7 can make the tweezers arm 2 of both sides be close to simultaneously or keep away from when rotating, makes the tweezers arm 2 centre gripping or unclamp, and when tweezers arm 2 was close to in addition, the screw hole 12 spiro union on the tweezers arm 2 was on screw rod 8, can automatic locking at any time, automatic locking need not manual continuous hard after making the tweezers arm 2 centre gripping, and compression spring 11 can give 2 outside elastic thrust of tweezers arm of both sides, can make the tweezers arm 2 of both sides keep the interval on guide bar 9 from top to bottom, and is more level and smooth stable when tweezers arm 2 is close to the centre gripping.

In this embodiment, a hanging rod 4 is fixed on the outer wall of the lower end of the handle 1 in a threaded manner, and a hanging ring 5 is movably inserted on the hanging rod 4. The surgical forceps can be conveniently hung and placed by arranging the hanging ring 5.

During the use, handheld handle 1 rotates adjust knob 7 with the thumb and can make the tweezers arm 2 of both sides simultaneously inwards be close to, makes tweezers head 3 will treat the centre gripping article centre gripping, and the stall, the centre gripping of tweezers arm 2 can automatic locking, can carry out follow-up operation, when needing to loosen the article of centre gripping, can the antiport adjust knob 7, makes both sides tweezers arm 2 outwards keep away from simultaneously, makes tweezers head 3 loosen the article of centre gripping.
