Description

A kind of tissue folder clamped

Technical field

The utility model relates to a kind of medical instruments, and in particular to the tissue folder that one kind can clamp.

Background technique

Tissue folder, also known as blood vessel clip, ligation clip, hemostatic clamp, in surgical operation (mainly minimally invasive laparoscopic surgery) Folder closes blood vessel and pipeline tissue.Such as gall-bladder is closed for folder in cholecystitis, calculous cholecystitis, gallbladder polyps patient's cholecystectomy Pipe and cystic artery play hemostasis, ligation closure function.The blood vessel of early stage or the common method of tissue ligation are that needlework coincide, But needlework coincide the inevitable defects such as that there are blood vessel internal membrane damages is larger, anastomosis procedure is complicated, takes long time, therefore from blood The trend that gradually substituted needlework coincide since pipe clamp comes out.Initial blood vessel clip based on metal material, as titanium folder, silver brain clip, Stainless steel clamp etc., such blood vessel clip is although cheap, easy to use, but tends to occur loosening, vacillating, falling off too early Phenomenon, and can the postoperative optical image diagnosis of interference effect in indwelling body；As thyrite good fortune company in 1999 releases Brunswick folder, no Absorbable clips are opened up markets gradually, become the new selection mode of one kind of tissue ligation, and Brunswick folder is improved from structure design Occur loosening, phenomena such as vacillating or falling off too early, in indwelling body can also will not the postoperative optical image diagnosis of interference effect, but it is long Potential hazard can be still generated in phase indwelling body.Recently as the development of absorbable material, absorbable biological folder enters the market gradually, but It is a variety of that there are still Pressure values is insufficient for current Absorbable clips, anti-slip power is insufficient, laparoscope clamp process is easy to happen offset etc. Problem.

US7326223 discloses ligation clip (the LIGATING CLIP WITH INTEGRAL with integral cutting guide rail CUTTING GUIDE), specifically disclosing hemostatic clamp is two arm configuration of V bifurcated, by safe catching lock, elastic hinge, arcuate nail leg (clamp), integrated anti-slop serrations and five part of knuckle composition.But there are still some problems in use, is mainly manifested in securely Property not enough, blood folder use process in will appear locking position slip.

203776976 U of CN discloses a kind of hemostatic clamp of anti-dropout, specifically disclose including be arcuate structure One clamp arm and the second clamp arm, using elastic hinge connection, free end is mutually matched buckle structure for one end of two clamp arm, is led to Crossing one group is yin-yang fastening structure, the secure latch being mutually locked, to improve fastness.However, but anti-dropout hemostatic clamp it is real The effect of border application is limited.

To sum up, the prior art still lacks a kind of tissue folder, and clamp process when operation can effectively be overcome to be easy to happen offset The problem of.

Utility model content

The utility model aim is on the basis of existing technology, to provide a kind of tissue folder with snap device, Ke Yifang Just tissue is clipped in actual use, overcomes the problems, such as that clamp process shifts.The technical solution of the utility model is specific as follows It is described:

A kind of tissue folder clamped, including the first clamp arm and the second clamp arm by elastic hinge connection, described the One clamp arm and the second clamp arm are arcuate structure and radian mutually coincide, the freedom of the free end of the first clamp arm and the second clamp arm End is mutually matched buckle structure, and the outer surface of first clamp arm free end is provided with the first cylindrical knuckle, described The surface of first knuckle is radially provided with several buckles.The tissue folder of the present apparatus when in use, can be by applying Binder clamps buckle, more firmly fixes tissue folder, the offset for effectivelying prevent tissue to press from both sides by buckle.

Preferably, the free end of first clamp arm is set as hook portion, the free end of second clamp arm be set as with The connection of the hook portion Yu the first clamp arm arcuate structure is arranged in the hook groove that the hook portion matches, first knuckle Place, first knuckle run through first clamp arm.The junction of tissue folder is stress concentration point, that is, is easy to happen rupture Place, here, the stability of single unit system on the one hand can be enhanced in knuckle and buckle setting, on the other hand solid using buckle It surely is more firm.First clamp arm, second clamp arm, the hook portion, the hook groove, first knuckle and described What buckle was integrally formed, molding is moulded by a mold.

Preferably, the buckle is arc-shaped.

Preferably, the buckle quantity is 2, the edge of the buckle is concordant with the edge of first clamp arm.Two A buckle with the axis of the first clamp arm be it is arranged symmetrically, when use, will not more shift.

Preferably, the radian of the buckle is 15-200 °.Preferred value is 180-190 °.

Preferably, the diameter of first knuckle is 0.5-5mm, the height of the buckle is 0.1-2mm, and width is 0.01-0.5mm。

Preferably, the diameter of first knuckle is 1-2mm, the height of the buckle is 0.15-0.5mm, preferred value For 0.2mm, width 0.05-0.2mm, preferred value 0.2mm.

Preferably, first knuckle and the first clamp arm intersection are along the section face of the first knuckle sidewall direction Product is 0.5-2.0mm²。

Preferably, the both ends of the hook groove, using the axis of the second clamp arm as axisymmetrical setting, there are two cylindrical Second knuckle.Second knuckle is also a stress concentration point, and the structure that the second knuckle of setting can be such that tissue presss from both sides is firmer.

Preferably, the second knuckle diameter be 1-4mm, be highly 1-2mm, second clamp arm with the second knuckle Junction junction area 0.5-2.0mm²。

The beneficial effects of the utility model have:

(1) it is buckled by being arranged in the first knuckle, two sides is buckled by applicator clamping when use, it can be more firmly Fix tissue folder, the offset for effectivelying prevent tissue to press from both sides；

The junction of hook portion Yu the first clamp arm arcuate structure is set in (2) first knuckles, the stability of device can be increased；

(3) present apparatus design is rationally, easy to use, at low cost, can effectively promote and apply.
