Problems solved by technology

[0002] The existing cervical sampler controls the opening and closing of the movable jaws by pressing the movable clamp handle and stretching the traction cable, and takes samples through the cooperation of the movable jaws and the fixed jaws. However, since the fixed jaws and the movable jaws are both thick round The arc-shaped structure makes it difficult to stay on smooth and curved tissue surfaces such as the cervix for tissue grasping and sampling, and it is easy to make the sampler slip off. operation time

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figure 1-4 As shown, a cervical sampler includes a forceps body 1 and a sampling structure arranged at the end of the forceps body 1, and the sampling structure includes a sampling tube I2 and a sampling tube II3 respectively arranged at the ends of the two forceps arms of the forceps body 1 , the sampling tube I2 and the sampling tube II3 are mutually nested tubular structures, the upper and lower ends of the tubular structure are connected, the outer diameter of the sampling tube I2 is not greater than the inner diameter of the sampling tube II3, and the side walls and top surfaces of the sampling tube I2 and the sampling tube II3 are respectively The limit thorns 4 are set, and the limit thorns 4 of the sampling pipe I2 and the sampling pipe II3 are arranged opposite to each other.

[0025] The clamp body 1 includes a clamp arm...

Abstract

The invention discloses a cervix uteri sampler. The sampler comprises a forcep body and a sampling structure, the sampling structure comprises a sampling tube I and a sampling tube II, the sampling tube I and the sampling tube II are of tubular structures and are connected with each other in a sleeving way, the upper end and the lower end of the tubular structures are through, the external diameter of the sampling tube I is not larger than the inner diameter of the sampling tube II, the top faces of the sidewalls of the sampling tube I and the sampling tube II are respectively provided with limit thorns, and the limit thorns of the sampling tube I and the sampling tube II are arranged oppositely. The cervix uteri sampler has the advantages that the location is accurate, sampling operationis simple and rapid, the sampler can be applied to sampling of various smooth and curved tissue surfaces, and the situation that the sampling cannot be carried out because the sampler cannot fix tissues does not happen; as the sampling tube I and the sampling tube II have certain shapes and thicknesses, the tissues with different thicknesses and positions can be selected according to the amount ofthe sampling, the sampling is carried out by enabling the sampling tube I and the sampling tube II to be connected in a sleeving way after the location is carried out by the limit thorns, and the problems that an existing sampler is small in sampling amount, multiple times of sampling are needed, more damage points are caused to cervix uteri are solved.

Description

technical field [0001] The invention belongs to the technical field of surgical instruments, and in particular relates to a cervical sampler. Background technique [0002] The existing cervical sampler controls the opening and closing of the movable jaws by pressing the movable clamp handle and stretching the traction cable, and takes samples through the cooperation of the movable jaws and the fixed jaws. However, since the fixed jaws and the movable jaws are both thick round The arc-shaped structure makes it difficult to stay on smooth and curved tissue surfaces such as the cervix for tissue grasping and sampling, and it is easy to make the sampler slip off. operation time. Contents of the invention [0003] The object of the present invention is to provide a cervical sampler to solve the above problems. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A cervical sampler, comprising a forceps body and a s...
