Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Such as figure 1 , 2 , 3-1 and 3-2, a kind of tissue forceps for digging out hidden lesions in the deep side, consists of two clamp arms arranged in parallel, each clamp arm is composed of hinged forearm 2 and rear arm 1 Wherein the front ends of the two forearms 2 are all set as serrated on the opposite side, so that when the two are close to each other, a clamp 21 is formed, which is convenient to clamp the diseased tissue; the clamp 21 is in an open state when not in use . And the rear ends of the two forearms 2 are connected with the front pin shaft 4 near the joint 5 of the rear arm 1 hinge, so that the front and back ends of the forearm can be used for lever movement through the connection of the front pin shaft 4. The clamp 21 will be in a clamping state.

[0031] The two rear arms 1 are connected by the rear pin shaft 3 near the hinge...

Abstract

The invention discloses a tissue forceps for removing hidden deep lesions, which is composed of two clamp arms arranged in parallel, and each clamp arm is composed of a hinged forearm and a rear arm; the front ends of the two forearms are opposite to each other. The sides are all set in a serrated shape to form a clamp, and the rear end is connected by a pin shaft near the hinge; the two rear arms are connected by a pin shaft near the hinge. The present invention is composed of two clamping arms arranged in parallel, and the two clamping arms are composed of two sections, and the corresponding positions of the front and rear sections are pin-connected, which reduces the clamping displacement of the clamping arms and is convenient to use. When removing deep hidden lesions, the operation can be performed on the diseased tissue, and under the action of the protective plate, the shallow normal tissue can be effectively protected; and the direction of the clamp is at a certain angle with the plane of the entire tissue clamp. More convenient and effective removal of diseased tissue.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tissue forceps for removing deep hidden lesions and protecting normal tissue structures. Background technique [0002] With the development of the modern medical model to the social-psychological-physiological model, patients suffering from neurological diseases have gradually improved their quality of life requirements, and the minimally invasive neurosurgery that emerged at the historic moment requires minimal damage to normal neural structures and maximum Excision of abnormal lesions or tumor tissue. During neurosurgery, it is often encountered that abnormal lesions or tumor tissues are hidden deep in the normal brain, spinal cord, nerves, and blood vessels. Most of the neural structures, such as the spinal cord, cannot be retracted to one side. In the limited space of the cranial cavity and spinal canal, it is difficult to protect the normal tissue structure and co...
