Description

Testicle piercing depth

Technical Field

The utility model relates to the field of medical equipment, especially a testicle piercing depth.

Background

Currently, in clinical work, there are two methods for testicular biopsy: 1. when the operation is released for incision biopsy, the method needs two or more persons to operate in a matching way, and the wound is relatively large. 2. Although the puncture biopsy is performed by a common needle injector, the method has the following two defects although the trauma is small: firstly, the testicle tissue extracted by a single puncture is less, even the testicle tissue can not be extracted sometimes, so that repeated puncture (for diagnostic testicle puncture, if the tissue is less, only the existence of sperms can be simply evaluated, but no more testicle tissue can be extracted, so that pathological examination can not be carried out, for a patient who is treated by a test tube infant, if the tissue is less, the quantity of sperms is correspondingly less, and the sperm is inconvenient to be preferred) is difficult to avoid damaging the testicle function. Secondly, when carrying out the testicle puncture, the operator fixes the testicle in one hand, and the other hand needs to continuously control the syringe to the pull piston, in order to produce continuous negative pressure, thereby reach the purpose, but the repeated pull piston can lead to the operator tired, produces the negative pressure inadequately, leads to the pjncture needle to deviate from the testicle even, causes to aspirate the unexpected damage that testicle tissue was extracted to it.

Chinese patent publication CN208355495U discloses a testicle biopsy device, which can extract testicle tissue and relieve the fatigue of the operator, but the utility model is not enough, and when the piston is drawn repeatedly, the drawing action of the operator is easily blocked by the case, so that the drawing action is not smooth. When the clamping shell is repeatedly pulled and pulled, the hand of an operator is easily affected by the clamping shell to shake, the puncture needle can be separated from the testis, and the patient is injured.

3. Because be equipped with the scale on the syringe needle lateral wall, can show the syringe needle and get into the degree of depth in the testicle, and then medical staff can accurately hold the position of extracting the testicle tissue, makes things convenient for medical staff to extract the testicle tissue.

4. Because be equipped with linear anti-skidding line on the cylinder lateral wall to increase the frictional force of medical staff's hand and cylinder, prevent that medical staff from taking place the smooth phenomenon of hand when carrying out the pull action, avoid haring the patient because of the error.

5. The upper end of the movable rod is fixedly provided with the handle, so that medical staff can push and pull the movable rod repeatedly, the hand fatigue of the medical staff is relieved, and the working strength of the medical staff is reduced.
