Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical forceps technology, and in particular to a forceps for pathological sampling of biopsy specimens. Background Technology
[0002] Pathological forceps are specialized tools used for grasping, fixing, and turning tissue specimens. In pathological sampling, they are suitable for grasping organ specimens and larger tissues and moving them to the desired location. Biopsy specimens refer to smaller tissues, typically only 1 to 2 mm in diameter, which need to be grasped from the bottom of a bottle containing fixative and placed in an embedding cassette for further processing.
[0003] Current pathology forceps are medical forceps with flat, non-concave tips, which makes them prone to slipping when handling biopsy specimens. This causes the specimen to slip out of the forceps' control and fall onto the sampling stage, increasing the time required for re-grasping and increasing the risk of specimen loss. Furthermore, when handling specimens immersed in liquid, the light tissue and the existing forceps cause the liquid to agitate, making the specimen difficult to grasp. Additionally, the non-removable tips of current technology necessitate replacing the forceps themselves after prolonged use, increasing operating costs.
[0004] To address this, we designed a forceps for pathological sampling of biopsy specimens. Utility Model Content
[0005] The purpose of this invention is to provide a type of forceps for pathological sampling of biopsy specimens, which addresses the problem of low efficiency in the existing technology for handling biopsy specimens.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A forceps for pathological sampling of biopsy specimens includes a forceps body and clamping heads symmetrically arranged at the bottom end of the forceps body, and further includes;
[0008] An anti-detachment component, comprising a mesh screen disposed on a clamping head, a plurality of plastic parts disposed on the sidewall of the mesh screen, and a buckle groove disposed on the plastic parts;
[0009] A connecting component is disposed between the tweezers body and the gripping head, and is used to adjust the disassembly and installation of the gripping head on the tweezers body.
[0010] Preferably, the tweezers body is provided with a fixing component, the fixing component including a first cavity disposed in the tweezers body, a second cavity disposed in the first cavity, a plurality of insertion blocks disposed in the second cavity, and a hole disposed on the outer wall of the tweezers body.
[0011] Preferably, the clamping head is provided with a docking assembly, which includes a clamping rod disposed at the tail end of the clamping head and a connecting body disposed at the end of the clamping rod.
[0012] Preferably, the connecting assembly includes a first extension plate disposed on the connecting body, a third cavity disposed on the connecting body, a fixing component disposed on the connecting body, and a second extension plate disposed within the connecting body.
[0013] Preferably, the fixing component includes an insertion hole disposed on the side wall of the first extension plate and a pressing block disposed on the side wall of the second extension plate.
[0014] Preferably, the tweezers body is provided with an anti-slip component, which includes a hand grip groove symmetrically arranged on the side wall of the tweezers body, a first anti-slip texture and a second anti-slip texture arranged in the hand grip groove.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1. This utility model, through the design of the clamping head and plastic parts, allows the mesh to be fixed to the clamping head via the buckle groove on the plastic parts when personnel need to clamp biopsy specimens in liquid bottles. This increases the contact area and friction coefficient of the clamping head under the support of the mesh, while reducing the disturbance of the clamping head to the biopsy specimen in the liquid, making it easier to clamp and avoiding slippage when clamping the specimen. At the same time, the mesh can reduce the squeezing damage to the specimen, thereby improving the clamping efficiency of biopsy specimens.
[0017] 2. With the addition of the first and second extension plates, this utility model allows for quick removal of the gripper head after repeated use and subsequent damage. This is achieved by pressing against the pressing block, which extends the service life of the tweezers and saves resources. Subsequently, the plastic parts can be pushed to quickly peel off the mesh, thus completing the disassembly process of the gripper head. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0026] Reference Figures 1-6 A forceps for pathological sampling of biopsy specimens includes a forceps body 1 and gripping heads 4 symmetrically arranged at the bottom of the forceps body 1. It also includes an anti-dislodgement component and a connecting component. The anti-dislodgement component mainly prevents the biopsy specimen from being difficult to grasp due to liquid agitation when gripping it, and avoids slippage and falling during the gripping process, thereby improving the efficiency of personnel in gripping the biopsy specimen. At the same time, the anti-dislodgement component can prevent the biopsy specimen from being squeezed and deformed after gripping, improving the reproducibility of the specimen. The connecting component mainly facilitates the replacement of gripping heads 4 by personnel, preventing the gripping heads 4 from being damaged and rusted from coming into contact with the specimen, which would cause the specimen to be contaminated and thus affect the pathological diagnosis of the disease.
[0027] When using the forceps body 1, personnel must ensure that the gripping head 4 has been installed through the connecting component. At this time, personnel can determine whether to install the anti-detachment component according to the object to be gripped. If the volume of the tissue to be gripped is large, the anti-detachment component does not need to be installed. If the tissue to be gripped is a biopsy specimen, the anti-detachment component can be installed on the gripping head 4 to grip the live tissue.
[0028] It should be noted that the gripping head 4 has a hollow center, is bent in shape and has an arc-shaped inner wall. The arc-shaped inner wall can better grip the biopsy specimen, and the hollow shape prevents the biopsy specimen from being squeezed when it is gripped and allows the liquid to flow out, reducing disturbance to the specimen.
[0029] The anti-detachment component includes a widened mesh 5 with an arc-shaped surface on the clamping head 4, several plastic parts 501 disposed on the side wall of the mesh 5, and a buckle groove 502 disposed on the plastic parts 501.
[0030] When the forceps body 1 used by the personnel needs to grasp the biopsy specimen, since the biopsy specimen is stored in a liquid bottle, it will become difficult to grasp during the grasping process due to agitation. At this time, the personnel can pull the forceps body 1 out of the bottle and wipe the gripping head 4 dry. Then, the end of the gauze 5 with the plastic part 501 is fastened to the gripping head 4. The fastening groove 502 on the plastic part 501 directly engages and abuts against the outer ring wall of the gripping head 4, so that the gauze 5 is fixed on the gripping head 4. At this time, the specimen in the bottle can be grasped. With the cooperation of the gauze 5, the specimen can be grasped quickly. At the same time, the gauze 5 wraps the specimen inside the gripping head 4, so that it will not be squeezed and cause tissue deformation, thereby improving the grasping efficiency of biopsy specimens.
[0031] It should be noted that the plastic part 501 is a plastic buckle in the prior art, which is engaged with the outer ring wall of the clamping head 4 by pressing to complete the fastening;
[0032] A layer of plastic needs to be fitted and fixed on the outer ring of the mesh 5 so that the mesh 5 can maintain tension and will not deform over a large area. Then, the plastic part 501 is fixed to this layer of plastic by gluing.
[0033] The mesh 5 has the same shape as the gripper head 4, both featuring a widened surface and a concave arc shape. The concave arc shape makes the mesh 5 fit the gripper head 4 better, improving the efficiency of personnel when gripping specimens.
[0034] The tweezers body 1 is provided with a fixing component, which includes a first cavity 101 disposed in the tweezers body 1, a second cavity 102 disposed in the first cavity 101, a plurality of insertion blocks 103 disposed in the second cavity 102, and a hole 104 disposed on the outer wall of the tweezers body 1.
[0035] The clamping head 4 is provided with a docking assembly, which includes a clamping rod 3 disposed at the tail end of the clamping head 4 and a connecting body 2 disposed at the end of the clamping rod 3;
[0036] The connecting component is located between the tweezers body 1 and the clamping head 4, and is used to adjust the disassembly and installation of the clamping head 4 on the tweezers body 1;
[0037] The connecting assembly includes a first extension plate 201 disposed on the connecting body 2, a third cavity 203 disposed on the connecting body 2, a fixing assembly disposed on the connecting body 2, and a second extension plate 204 disposed inside the connecting body 2.
[0038] The fixing assembly includes an insertion hole 202 disposed on the side wall of the first extension plate 201 and a pressing block 205 disposed on the side wall of the second extension plate 204.
[0039] When the operator needs to install the clamping rod 3, simply press the second extension plate 204 with one hand to compress the third cavity 203 and press it against the first extension plate 201. Then, align the connector 2 with the entrance of the first cavity 101 at the bottom of the tweezers body 1 and push it in. After pushing it in, release the hand that was pressing the connector 2. During the pushing process, the second extension plate 204 will gradually open due to the oblique opening of the first cavity 101 and release the third cavity 203. Then, the first extension plate 201 will enter the area of the second cavity 102 and insert the insertion hole 202 into the second cavity 102. When the insertion block 103 is inserted, the second extension plate 204 will also cause the pressing block 205 on the side wall to protrude from the hole 104 on the side wall of the tweezers body 1, thereby fixing the connector 2 inside the tweezers body 1. When the clamping head 4 is damaged and needs to be replaced, you only need to apply pressure to the pressing block 205 protruding from the hole 104 with one hand to compress the second extension plate 204 and press the third cavity 203 against the first extension plate 201. At this time, the other hand can move the clamping head 4 to loosen the first extension plate 201, and then the connector 2 can be disassembled to achieve the effect of quick replacement.
[0040] It should be noted that both the first extension plate 201 and the second extension plate 204 are made of stainless steel. The second extension plate 204 is supported by the third cavity 203, which makes the second extension plate 204 elastic on the basis of the connecting body 2. The second extension plate 204 can be installed and disassembled by pressing it against the first extension plate 201.
[0041] The tweezers body 1 is provided with an anti-slip component, which includes a hand grip groove 6 symmetrically arranged on the side wall of the tweezers body 1, a first anti-slip texture 601 and a second anti-slip texture 602 arranged in the hand grip groove 6;
[0042] To increase hand friction when using the tweezers body 1, a recessed hand grip groove 6 is used to increase the contact effect between the hand and the outer wall of the groove. At the same time, the first anti-slip texture 601 and the second anti-slip texture 602 inside are used to increase hand friction. The first anti-slip texture 601 and the second anti-slip texture 602 are in a protruding state, which makes the user experience better when using the hand or wearing gloves.
[0043] The working principle of this utility model is as follows:
[0044] When personnel need to retrieve specimens from liquid bottles, they simply fix the mesh 5 to the gripping head 4 via the plastic part 501, and then they can retrieve the living tissue in the bottle. The mesh 5, supported by the gripping head 4, effectively reduces specimen damage. Simultaneously, the mesh 5 increases the friction for retrieving specimens, improving the efficiency of retrieving specimens from liquids. If the mesh 5 becomes damaged or contaminated after prolonged use of the tweezers body 1, it can be removed from the gripping head 4 by wearing gloves, and a new mesh 5 can be installed. When the gripping head 4 is damaged, simply press the protruding pressing block 2 on the outer wall of the tweezers body 1 with one hand. 05 Apply pressure with one hand and pull the clamping head 4 with the other hand to loosen it. Then pull the connecting body 2 out of the first cavity 101 and replace it with a new clamping head 4. Simply press the second extension plate 204 with one hand to compress the third cavity 203 and press it against the first extension plate 201. Align it with the first cavity 101 and push it inward. Then the insertion hole 202 on the first extension plate 201 aligns with the insertion block 103. The second extension plate 204 slides in the obliquely opened first cavity 101 and protrudes after the pressing block 205 coincides with the hole 104 on the outer wall of the tweezers body 1. The installation process of the clamping head 4 is then completed. With the clamping head 4 and the plastic part 501, when personnel need to clamp the specimen in the liquid bottle, the mesh 5 can be fixed to the clamping head 4 through the buckle groove 502 on the plastic part 501. The clamping head 4 increases the coefficient of friction under the support of the mesh 5, reduces the disturbance of the specimen in the liquid, avoids slipping and falling during the clamping process, and makes it easier to clamp.
