Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-Figure 3 As shown, a single-hole endoscopic incision retractor dilator 1 includes a dilator body 1, a first dilator ring 2 provided at the upper end of the dilator body and a second dilator ring 3 provided at the lower end of the dilator body, and the dilator body The height of 1 is 25-80mm, the diameter of the first expansion ring 2 is larger than the diameter of the second expansion ring 3, the diameter of the first expansion ring 2 is 25-100mm, and the diameter of the second expansion ring 3 is 25-100mm. The body 1 is tubular, and the inner wall of the dilator body 1 is provided with a circular channel 4 for the passage of the thoracoscopic camera. The layer 5 is made of nylon material, and the thickness of the reinforcement layer 5 is 1-5 mm.

[0018] Method of use: When a patient needs to undergo single-port thoracoscopic surgery, an incisi...

Abstract

The invention relates to an incision dilator for a single-hole thoracoscope. The dilator comprises a dilator body, a first dilation ring arranged at the upper end of the dilator body and a second dilation ring arranged at the lower end of the dilator body, wherein the dilator body is tubular, a round channel allowing a thoracoscope camera to pass is formed in the inner side wall of the dilator body, a reinforcing layer is arranged on an inner ring of the round channel, and the diameter of the first dilation ring is larger than that of the second dilation ring. The incision dilator for the single-hole thoracoscope is simple in structure, compact in design and convenient to use, the reinforcing layer is arranged on the round channel allowing the thoracoscope camera to pass and can prevent the thoracoscope camera from compressing the dilator body during using, meanwhile, the thoracoscope camera is supported to a certain extent, deformation of the dilator body in an surgery process is avoided, an incision can be effectively prevented from retraction, and a smooth surgery is guaranteed.

Description

technical field [0001] The invention relates to a single-hole laparoscopic incision retractor dilator, which belongs to the technical field of medical devices. Background technique [0002] Single-port thoracoscopic surgery has been widely used clinically. Single-port thoracoscopic surgery requires only one 2-10 cm incision, and both the endoscope and surgical instruments pass through the same surgical incision. However, after the chest incision is completed, due to the automatic contraction of human tissues, the incision will gradually form a closed state with the prolongation of the operation time, which will cause certain difficulties to the operation. Instruments need to be carried out in coordination. Frequent entry and exit of the incision is likely to cause secondary damage to the incision, leading to infection of the incision, which is difficult to heal, and affects the recovery of the patient. Contents of the invention [0003] The purpose of the present inventio...
