Abstract

The utility model provides a pair of split-type disposable flexible biopsy forceps which comprises jaw components, a stem, a handle, a pull rod and actuators, wherein the stem is a metal hose, the pull rod is arranged inside the stem, the actuators are connected with the jaw components through the pull rod to control the jaw components to close or open, and the stem is connected with the handle through a movable connection structure. In the technical scheme provided by the utility model, since the part of the biopsy forceps, which is inserted into a human body, is connected with the handle which is outside the human body through only one movable connection structure, the part which is inserted into the human body can be designed for single use, and since the part which is outside the human body is not polluted, the part can be made of recyclable material. The split-type disposable flexible biopsy forceps eliminate cross infection and can be used repeatedly to the greatest extent.

Description

Split type disposable soft biopsy forceps

Technical field

This utility model relates to medical instruments field, particularly a kind of biopsy forceps, and this biopsy forceps utilizes the passage that is provided with in the endoscope, watches attentively down in endoscope people's in-vivo tissue is taken a sample.

Background technology

Human body being carried out in the diagnosis and treatment process, usually need carry out pathologic finding to intravital suspect tissue, generally all is suspect tissue is clamped next fritter and to take out and to do inspection through a kind of biopsy forceps during inspection; At present, when needing the intravital tissue of taking-up people to carry out biopsy, usually utilize equipment such as endoscope; Under the watching attentively of endoscope, suspect tissue is taken a sample, therefore; Have at present and much utilize sampling passage ad hoc in the endoscope, adopt a kind of soft biopsy forceps, Chinese patent notification number 201631250 just discloses a kind of soft biopsy forceps; This biopsy forceps comprises and is exposed at the outer biopsy forceps handle of ad hoc passage in the endoscope, generally is as scissors handle, has a fixed handle and a flexible handle; Be arranged on the duct-like claw beam in endoscope's designated lane; In claw beam, be provided with pull bar, at the not end of claw beam clamp be set, pull bar is controlled clamp and is unclamped and clamp to accomplish sampling under the control of flexible handle.Like this soft biopsy forceps and endoscope are used, under the watching attentively of endoscope, and the suspicious people's in-vivo tissue sampling that can exactly needs be taken a sample.But this biopsy forceps cost height is a kind of nonexpondable biopsy forceps, after sterilizing, reuse after using, and at present, and the biopsy forceps use after the sterilization completion still has the risk of cross infection.

Summary of the invention

The goal of the invention of this utility model is that present biopsy forceps is reused because the risk that sterilization thoroughly not possibly bring in order to overcome; And a kind of split type disposable soft biopsy forceps of design; Stretch into the interior position of patient body in this biopsy forceps and possibly contaminated part be designed to the split formula with handle part; Stretching into the intravital part of patient is disposable use, and handle portion is not owing to there be contaminated can the repeated use.

The technical scheme that this utility model goal of the invention adopts is: a kind of split type disposable soft biopsy forceps; Comprise clamp assemblies, claw beam, handle, pull bar, spanner, described claw beam is a metal hose, the described clamp assemblies of one of which termination; The other end is connected with described handle; Described pull bar is arranged in the described claw beam, and described spanner is connected with described clamp assemblies through described pull bar, controls described clamp assemblies clamping and perhaps unclamps; Described claw beam is connected by movable connection structure with described handle; Described movable connection structure comprises adapter sleeve; Described adapter sleeve is enclosed within described claw beam and connects outside the termination, in described adapter sleeve, be provided with described handle link on the female thread that is meshed of external screw thread; In described syndeton, described pull bar termination is provided with connecting ring, on described spanner, is connected with the hook that is connected with described connecting ring.

Further, in the above-mentioned a kind of split type disposable soft biopsy forceps: in the middle of described clamp assemblies, be provided with the location thorn.

[0006]In the technical scheme of this utility model; Owing to utilize a movable connection structure to be connected with external handle with stretching into intravital part in the biopsy forceps; Can process disposable outer body owing to do not relate to pollution with stretching into intravital part; Can adopt nonexpondable material, this product is when stopping cross infection, and maximum is reused the part apparatus with limiting the quantity of again.

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

The specific embodiment

Embodiment 1 is as shown in Figure 1.Present embodiment is a kind of split type disposable soft biopsy forceps; This soft biopsy forceps is particularly suitable for being arranged in the designated lane that is provided with in the endoscope; Under the watching attentively of endoscope; The tissue of doctor through clamp gripping patient internal lesions position takes out and detects, present embodiment comprise five parts such as clamp assemblies 1, claw beam 2, handle 3, pull bar 4, spanner 5; Outside the patient body, physician's hand handle 5 utilizes the perilesional suspect tissue of pull bar 4 control pincers assembly 1 grippings in the patient body to carry out biopsy through pulling spanner 5.Claw beam 2 is a metal hose in the product of present embodiment, one of which termination clamp assemblies 1, and the other end is connected with handle 3, and pull bar 4 is arranged in the claw beam 2, and spanner 5 is connected with clamp assemblies 1 through pull bar 2, and control clamp assemblies 1 clamps or unclamps as shown in Figure 2; The centre of clamp assemblies 1 is provided with location thorn 10 in the product of present embodiment, during use, utilizes location thorn 10 to penetrate into suspect tissue position in the focus earlier, carries out biopsy through clamp assemblies 1 gripping tissue then.Different with present biopsy forceps is, but the product separated into two parts of this utility model, and a part is to utilize to establish passage for biopsy forceps will in the medical apparatus and instruments such as endoscope and enter into the intravital part of patient; This part mainly contains the pull bar 4 in clamp part 1, claw beam 2 and the claw beam 2; Do not enter into intravital handle 3 parts when a part is to use in addition, stretch into intravital part and can make disposablely as requested, just become clinical waste after finishing once; Handle portion is owing to the reason of cost; Can use again by many short weights because it is not polluted, in the product in the present embodiment claw beam 2 with handle 3 be connected by movable connection structure; Like Fig. 3 and shown in Figure 4; Movable connection structure comprises adapter sleeve 6, and adapter sleeve 6 is enclosed within outside the claw beam 2 connection terminations 7, in adapter sleeve 6, be provided with handle 3 links on the female thread that is meshed of external screw thread; In syndeton, the pull bar termination is provided with connecting ring 8, on spanner 4, is connected with the hook 9 that is connected with connecting ring 8.
