Description

Epididymis piercing depth

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to epididymis piercing depth.

Background

The epididymis is an organ formed by a plurality of tortuous and tiny tubes, one side of the epididymis is connected with the vas deferens, and the other side of the epididymis is connected with the seminiferous convoluted tubule of the testis. When the sperm leaves the testis, it runs into the epididymis and continues to grow and mature. Epididymis is at the upper end and the rear edge of the testis, epididymal duct is about 4-5 m long, and the coil forms a body part and a tail part to help the sperm to mature.

Epididymis puncture is an operation, and the injection operation in the single sperm egg cell is carried out by using the sperms obtained by epididymis puncture, so that countless patients with obstructive azoospermia have own offspring. The traditional epididymis puncture is to directly use a syringe to extract the sperms in the epididymis, and the following problems exist in the way: firstly, two medical staff are needed to complete the operation, because in the operation process, one of the medical staff needs to hold the testis of a patient by hands, and then the other medical staff uses an injector to puncture, the labor is wasted; secondly, medical care personnel hold the syringe with the hand and puncture the in-process, can be difficult to avoid appearing rocking, will bring very big misery to the patient like this.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model aims at providing a reduce the manpower and can avoid the puncture in-process appearance epididymis piercing depth who rocks again simultaneously.

In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides an epididymis piercing depth, includes bed board and a plurality of support columns of fixed connection in the bed board bottom, one side of bed board is equipped with the breach, the bottom fixedly connected with of breach is used for placing the testicle and the mantle of making by transparent material, the up end of mantle and the upper surface of bed board are located same horizontal plane, be equipped with the puncture hole on the mantle, fixedly connected with linking arm between the both sides wall of breach, be equipped with electric putter on the linking arm, it has the connecting axle still to sliding connection between the both sides wall of breach, the connecting axle is located between linking arm and the mantle, can dismantle on the connecting axle and be connected with the syringe, be connected with the pjncture needle on the syringe, the needle point and the puncture hole of pjncture needle are just to setting up.

The utility model discloses a theory of operation:

when the epididymis puncture device is used, a patient lies on a bed plate firstly, a notch is formed in one side of the bed plate, a shell sleeve used for placing a testis is fixedly connected to the bottom of the notch, so that when the patient lies down, two legs stretch, the testis of the patient is placed in the shell sleeve, the two legs are just placed on the bed plate on two sides of the notch, an electric push rod on a connecting arm is started, the electric push rod starts to extend, the free end of the electric push rod is fixedly connected with the connecting shaft, the connecting shaft is connected between two side walls of the notch in a sliding mode, the connecting shaft is pushed to slide in the extending process of the electric push rod, an injector is driven to move, the needle point of a puncture needle on the injector is arranged opposite to a puncture hole in the shell sleeve, the puncture needle enters into the epididymis in the moving process of the puncture hole, after the puncture needle enters into the epididymis, the electric push rod is closed, then the piston of the injector is pulled to move, so that the extraction of sperms in the epididymis can be completed, after the extraction is completed, the electric push rod is started again, and meanwhile, the electric push rod is controlled to retract, so that the puncture needle can be pulled out of the epididymis, and then the injector is taken down, so that the operation can be completed.

The utility model has the advantages that:

when this scheme of adoption is the epididymis puncture for the patient, only need the patient to lie on the bed board, then put into the shell with patient's testicle, then remove and then just can drive the pjncture needle removal on the syringe through control electric putter, the pjncture needle just can puncture the testicle in the shell through the puncture hole on the shell. Compared with the prior art, when the epididymis puncture is carried out by adopting the epididymis puncture device, only one medical worker is needed to complete the operation, the labor is saved comparatively, and the medical worker does not need to hold the injector with hands to puncture in the puncture process, so that the shaking cannot occur in the puncture process, the puncture process is more stable, and the pain of a patient is reduced as much as possible.

Furthermore, a through hole is formed in the connecting shaft, the injector is located in the through hole and is in sliding connection with the through hole, and a butting piece used for fixing the injector is detachably connected to the connecting shaft. By adopting the connection mode, after the puncture operation is completed, when the injector needs to be taken down, the abutting part only needs to be taken down, and then the injector is pulled to slide until the injector is separated from the connecting shaft, so that the operation is more convenient and labor-saving.

Further, the abutting piece is a screw, and the screw is in threaded connection with the connecting shaft. The screw is simple in structure and convenient to machine and produce, and the mode of threaded connection is simple, so that convenience is provided, and time and energy spent in the machining and producing process are saved.

Further, the inner wall of the shell is provided with a transparent silica gel layer. Because the texture of the silica gel layer is soft, after the testis of the patient is contacted with the silica gel layer, the comfort of the patient is increased.
