Abstract
The utility model discloses a positioning puncturing knife for an arthroscopic surgery. The positioning puncturing knife comprises a hollow structure type puncturing needle with a needle handle. A cutting knife provided with a cutting edge at the front end part is slidably sleeved on the puncturing needle; and scales are axially arranged on the outer surface of the cutting knife. Scales are arranged on the outer surface of the puncturing needle. The cutting edge of the cutting knife is in a symmetrical double-cutting edge structure, and the cutting edge is 10 mm in width. The positioning puncturing knife provided by the utility model has the advantages of simple structure, low manufacturing cost, accurate positioning in use, small damages of the cutting edge, and easiness of knowing a puncturing depth. The positioning puncturing knife integrates three functions of puncturing and positioning, extracting synovial fluid and accurately cutting the puncturing point, so as to simplify surgery steps, in particular conveniently carry out cutting operations of a portal for a knee arthroscopy and an operation entry for a shoulder arthroscopy. The positioning puncturing knife provided by the utility model can be used as a normal machine for the arthroscopic surgery.
Description
Technical field
This utility model relates to arthrocsopic surgery and uses conventional apparatus, especially relates to a kind of arthrocsopic surgery localised puncture cutter.
Background technology
Arthroscope is the bar-shaped optical instrument about a kind of diameter 5mm that observes the joint internal structure, is the endoscope that the doctor is used for the diagnosis and treatment joint diseases.When doing arthrocsopic surgery; The doctor cuts two to three otch around corresponding joint; Arthroscope is put into intraarticular from an otch, and arthroscope links to each other with monitor through lead, and the inner structure in joint just can directly show on monitor; The doctor can make the IA state of an illness and clarifying a diagnosis, and puts into operating theater instruments from other otch simultaneously IA pathological changes is handled.The at present used conventional apparatus that articular cavity was punctured, extracted joint fluid is the sharp knife of function singleness; Need during use to cut with the skin and the muscle of sharp knife earlier with the point of puncture place; Re-use syringe and carry out drawing liquid, operating procedure complicacy and otch wound are big, and the otch size is irregular; Locate inaccurately, cut the bad grasp of the degree of depth.
Summary of the invention
The purpose of this utility model is to provide a kind of arthrocsopic surgery localised puncture cutter that integrates puncture location, point of puncture incision and extract three kinds of functions of joint fluid.
For realizing above-mentioned purpose, this utility model can be taked following technical proposals:
The described arthrocsopic surgery localised puncture of this utility model cutter comprises the puncture needle of the hollow structure that has needle handle, and slip cap is equipped with the cutting knife that leading section has cutting edge on the said puncture needle, and the outer surface of said cutting knife is provided with scale vertically.
The outer surface of said puncture needle is provided with scale.
The cutting edge of said cutting knife is symmetric double blade structure, and edge width is 10mm.
The advantage of this utility model is simple in structure, cheap; Accurate positioning during use, otch wound be little, thrust the degree of depth is easy to grasp; Have puncture location, extraction joint fluid and accurate three kinds of functions of otch point of puncture in one; Simplify operating procedure, especially made things convenient for the incision operation of knee joint mirror approach, shoulder joint videoendoscopic surgery inlet.Can be used as the conventional apparatus of arthrocsopic surgery.
Description of drawings
Fig. 1 is the structural representation of this utility model.
The specific embodiment
As shown in Figure 1; The described arthrocsopic surgery localised puncture of this utility model cutter; Comprise the puncture needle 2 of the hollow structure that has needle handle 1, the outer surface of puncture needle 2 is provided with scale, and slip cap is equipped with the cutting knife 4 that the leading section symmetry has double blade 3 on the puncture needle 2; Cutting edge 3 width are 10mm, are provided with scale vertically at the outer surface of cutting knife 4.
During operation; At first confirm to thrust the location with puncture needle 2 behind the arthrocentesiS position; Observe scale on the puncture needle 2 and grasp and thrust the degree of depth, get into behind the articular cavity, promote cutting knife 4 then forward the needle handle 1 extraction joint fluid that links to each other with syringe commonly used; Thrust articular cavity and observe the scale on the cutting knife 4 with double blade 3, grasp and to thrust the degree of depth and meet requirements of operation and can extract.One step was accomplished puncture location, drawing liquid and the incision of articular cavity, had simplified operating procedure greatly.
