Problems solved by technology

[0002] The current technique of transurethral resection of the prostate is to use the electric cutting ring to perform electric resection on the prostate tissue. To remove the hyperplasia of the prostate, the electric cutting ring needs to be cut one by one, and a blood vessel needs to be cut multiple times before hemostasis, which is difficult to completely remove. Hypertrophic glands, residual glands are the source of long-term UTIs

Embodiment Construction

[0008] The following embodiments are described by taking intravesical urethral surgery as an example, but the application of the present invention is not limited to intravesical urethral surgery. The invention can be applied to various operations requiring safe and fast cutting of tissues and organs. Such as laparoscopic myomectomy.

[0009] Such as figure 1 As shown, the embodiment of the present invention provides a prostate tissue chopper; including: an outer sheath 4; a pair of gears 3 are installed inside the outer sheath 4, and the gears 3 are engaged with a threaded pull handle 5, said Pulling the handle 5 can extend the outer sheath 4 to move longitudinally, and when the pulling handle 5 moves, the moving directions of the two gears 3 are the same; there are steel wires 1 on the two gears 3, and the heads of the steel wires 1 protrude from the outer sheath 4 to form a ring. A handle 2 is connected to the outer sheath 4 . A ring 6 is installed on the pull handle 5 ....

Abstract

The invention discloses a prostate tissue mincer which comprises a sheath, wherein a pair of gears are installed in the sheath, the gears are meshed with a threaded pull handle, the pull handle can longitudinally move along the sheath, and the two gears rotate in the same moving direction when the pull handle moves; and a steel wire is wound around the two gears, and the head of the steel wire extends out of the sheath to form a ring. The prostate tissue mincer can be used with a urethra / bladder operation endoscope, i.e. after integrally taking out the prostate, the body of the prostate can be minced into pieces by using the prostate tissue mincer in the bladder, and the pieces are safely removed with tongs. The prostate tissue mincer enhances the safety, causes no thermal damage, quickens the operation speed, saves the operation time and lowers the operation risk.

Description

technical field [0001] The present invention relates to a surgical instrument. Background technique [0002] The current technique of transurethral resection of the prostate is to use the electric cutting ring to perform electric resection on the prostate tissue. To remove the hyperplasia of the prostate, the electric cutting ring needs to be cut one by one, and a blood vessel needs to be cut multiple times before hemostasis, which is difficult to completely remove. Proliferated glands, residual glands are the source of long-term urinary tract infections. And there may be serious complications such as cutting through the bladder neck, cutting through the prostate capsule and damaging the rectum. Those with more residual prostate glands may have difficulty urinating after surgery. The tissue resected by the electrosurgical ring was in a strip shape, and it was difficult to distinguish the pathological location of the lesion after the operation. A large number of strips of ...
