Abstract
The utility model relates to the medical apparatus field, concretely a living tissue puncture device for pathological section, comprising a handle, a sleeve tube, a biopsy needle, a top seat, a piston, a spring and a spring catch, characterized in that: continuous grooves are arranged at the two sides of the handle and the spring catch is fixedly connected with the piston by passing through the continuous grooves at the two sides of the handle to make the piston under uniform stress by the elastic force of the spring with low friction coefficient. The needle head of the biopsy needle is in spearhead shape to be favorable for punching the pathological living tissue. An annular edge is arranged at the front end of the sleeve to be favorable for cutting the pathological living tissue. The living tissue puncture device has advantages of reasonable structure, convenient and quick use and no loss of pathology tissue.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind ofly cuts the living tissue perforator that is used for pathological section that tissue carries out check pathological section from the swollen unusually thing of human body.
Background technology
At present, patient for superficial lesions such as prostate piece, mammary gland tumor, lymphadenectasis, need cut the chemical examination of cutting into slices of pathology living tissue, state of an illness weight with the patient diagnosed, when cutting pathological tissue, the doctor uses biopsy needle usually, and biopsy needle needle body or sleeve pipe sidewall have groove (or a plurality of little groove), by tissue elasticity or apply external force and make and organize in the embedded groove, cut out specimen by squeezing; Also has a kind of biopsy needle, it is provided with handle, sleeve pipe, biopsy needle, footstock, piston, spring and spring hitch, casing pipe sleeve is connected on the biopsy needle, handle in a tubular form, handle rear end is fixedlyed connected with footstock, fixedly connected with footstock in the biopsy needle rear end, be provided with piston in the handle, fixedly connected with piston in the sleeve pipe rear end, be socketed with spring on the biopsy needle between footstock and the piston, handle one side of spring is provided with groove relatively, the groove that spring hitch passes handle one side is connected with piston thread, make sleeve pipe concordant with the biopsy needle front end, biopsy needle nook closing member top is provided with the nook closing member groove, during operation, earlier with thumb with spring hitch toward post-tensioning, holddown spring, at this moment the biopsy needle front end exposes the nook closing member groove, treat that syringe needle enters the swollen unusually object location of human body after, pull the spring hitch that triggers spring with thumb, utilize the restorative impulsive force of spring to promote sleeve pipe forward, tissue under cutting is resided in the nook closing member groove its deficiency: the one, spring hitch is located at a side, the piston discontinuity, the 2nd, the specimen structure has some damage, the reliability and the pathological diagnosis accuracy rate of influence puncture.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, and the living tissue perforator that is used for pathological section that takes out specimen under a kind of novel structure, easy to use, the situation that can not squeezed, press, draw, turn round at biological tissue is provided.
The technical scheme that its technical problem that solves this utility model adopts is:
A kind of living tissue perforator that is used for pathological section, handle, sleeve pipe, biopsy needle, footstock, piston, spring and spring hitch, the both sides that it is characterized in that handle are provided with groove, the groove that spring hitch passes the handle both sides is fixedlyed connected with piston, it is evenly stressed through the elastic force of spring to be beneficial to piston, and coefficient of friction is low.
The biopsy needle syringe needle is spearhead shape in this utility model, the pathology living tissue that is beneficial to puncture, and the sleeve pipe front end is provided with circular blade, is beneficial to cut the pathology living tissue.
During this utility model operation, earlier pin footstock with thumb, with middle finger and forefinger with spring hitch toward post-tensioning, holddown spring, at this moment the biopsy needle front end exposes the syringe needle of spearhead shape, treat that syringe needle enters the swollen unusually object location of human body after, pull the spring hitch that triggers spring with thumb, utilize the restorative impulsive force of spring to promote sleeve pipe forward, the circular blade of sleeve pipe front end cuts down pathological tissue fast through the restorative impulsive force of spring, and the tissue under will cutting resides in the sleeve pipe.
This utility model is owing to adopt said structure, has rational in infrastructurely, easy to use, quick, do not lose advantages such as pathological tissue.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Reference numeral: handle 1, sleeve pipe 2, biopsy needle 3, footstock 4, piston 5, spring 6, spring hitch 7, syringe needle 8, circular blade 9
The specific embodiment:
Below in conjunction with accompanying drawing this utility model is further specified:
A kind of living tissue perforator that is used for pathological section, handle 1, sleeve pipe 2, biopsy needle 3, footstock 4, piston 5, spring 6 and spring hitch 7, sleeve pipe 2 is socketed on the biopsy needle 3, handle 1 in a tubular form, fixedly connected with footstock 4 in handle 1 rear end, fixedly connected with footstock 4 in biopsy needle 3 rear ends, be provided with piston 5 in the handle 1, fixedly connected with piston 5 in sleeve pipe 2 rear ends, be socketed with spring 6 on the biopsy needle 3 between footstock 4 and the piston 5, it is characterized in that the both sides of handle 1 are provided with groove, the groove that spring hitch 7 passes handle 1 both sides is fixedlyed connected with piston 5, it is evenly stressed through the elastic force of spring 6 to be beneficial to piston 5, and coefficient of friction is low.
During this utility model operation, earlier pin footstock 4 with thumb, with middle finger and forefinger with spring hitch 7 toward post-tensionings, holddown spring 6, at this moment biopsy needle 3 front ends expose the syringe needle of spearhead shape, treat that syringe needle enters the swollen unusually object location of human body after, pull the spring hitch 7 that triggers spring 6 with middle finger and forefinger, utilize spring 6 restorative impulsive forces to promote sleeve pipe 2 forward, the circular blade 9 of sleeve pipe 2 front ends cuts down pathological tissue fast through spring 6 restorative impulsive forces, and the tissue under will cutting resides in the sleeve pipe 2.
This utility model is owing to adopt said structure, has rational in infrastructurely, easy to use, quick, do not lose advantages such as pathological tissue.
