Embodiment 1

[0023] Such as Figure 1-4 As shown, a special separating forceps for transoral vestibular endoscopic thyroid surgery is mainly composed of a forceps head 1 and a forceps handle 2. The middle section of the forceps head 1 has a curved part 11 curved in a circular arc shape, and the two outer sides of the front portion 13 of the forceps head There are round and smooth protruding parts 12 protruding respectively.

[0024] Such as figure 1 , 2 As shown in and 4, the front section of the pliers head 1 also has a transition portion 16 extending straight out of the round and smooth protrusion 12, and the transition portion is connected with the curved portion.

[0025] Such as figure 2 As shown, the rounded protrusion 12 is integrally formed with the pliers head 1 and the thickness h of the rounded protrusion is equal to and flush with the thickness of the pliers head 1 .

[0026] Such as image 3 As shown, the radial, that is, the edge 14 in the width direction of the rounded...

Embodiment 2

[0034] This embodiment differs from Embodiment 1 in that: Figure 4 As shown, the circumferential edge of the thickness direction of the round and smooth protrusion 12 protrudes from the pincer head, that is, the thickness of the round and smooth protrusion 12 is greater than the thickness of the pincer head, and the circumferential edge of the round and smooth protrusion 12 is arc-shaped, smooth The maximum thickness i of the protruding part is 0.5-2.5 cm, preferably, the maximum thickness i of the round and smooth protruding part is 0.5-0.6 cm.

Abstract

The invention discloses special dissection forceps for endoscopic thyroid surgery through the oral vestibule. The special dissection forceps are mainly formed by a forceps head and a forceps handle; the middle section of the forceps head comprises the bending portion; two smooth protruding portions protrude out of the two outer sides of the front section of the forceps head respectively. According to the special dissection forceps for the endoscopic thyroid surgery through the oral vestibule, the special dissection forceps comprise the bending portion which can cross the lower jaw and accordingly blunt dissection can be performed on the lower jaw and the neck subcutaneous portion, the sufficient initial subcutaneous space is provided, and the operation space manufacture can be started under the good vision after a trocar, an endoscope and operating forceps enter into the operation space smoothly and the damage to the subcutaneous portion of the forceps head can be effectively avoided during subcutaneous dissection due to the fact that the two smooth protruding portions protrude out of the two outer sides of the front section of the forceps head respectively.

Description

technical field [0001] The invention relates to a medical device, in particular to a special separating forceps for thyroid surgery through oral vestibular endoscopy. Background technique [0002] Transoral vestibuloscopic thyroid surgery is favored by patients because of its excellent cosmetic effect and less trauma. During transoral vestibular thyroid surgery, it is necessary to bluntly dissect the subcutaneous part of the mandible so that the trocar (Trocar ) can enter the operation space smoothly, so that the endoscope and operating forceps have enough initial subcutaneous space to start to create enough operation space under a good view, reducing the risk of bleeding and unclear layers caused by blind separation. Separation of the mandible and subcutaneous neck through the oral vestibule needs to cross the mandible, and none of the surgical instruments currently used can meet the separation requirements. Contents of the invention [0003] Aiming at the technical prob...
