Detailed Description

Costal cartilage stripper include first pincers body 1 and second pincers body 2, first pincers body 1 and second pincers body 2 pass through articulated shaft 3 and articulate each other, first pincers body 1 and second pincers body 2 are crossed in articulated shaft 3 department and can use articulated shaft 3 to rotate as the centre of a circle, the front end of first pincers body 1 and second pincers body 2 is equipped with first splint 4 and second splint 5 respectively, the length direction of first splint 4 and second splint 5 all is parallel with the axle direction of articulated shaft 3, one side border installation slitting knife 6 of articulated shaft 3 is kept away from to first splint 4, slitting knife 6 sets up along the length direction of first splint 4, slitting knife 6 passes through bolt 7 and is connected with first splint 4, slitting knife 6's cutting part is the cockscomb structure, first splint 4 and second splint 5 surface in opposite directions all set up barbed nail 8. During operation, a doctor holds the holding parts at the rear parts of the first forceps body 1 and the second forceps body 2, separates the front ends of the first forceps body 1 and the second forceps body 2, enables the longitudinal cutting knife 6 and the second clamping plate 5 to be respectively positioned at two sides of the costal cartilage of the supply area, enables the length direction of the longitudinal cutting knife 6 to be consistent with the length direction of the costal cartilage of the supply area, then moves the longitudinal cutting knife 6 to a proper longitudinal cutting position in the middle of the costal cartilage of the area, clenches the first forceps body 1 and the second forceps body 2, enables the longitudinal cutting knife 6 to complete a through longitudinal cut on the costal cartilage, then maintains the clenching state of the first forceps body 1 and the second forceps body 2, twists left and right, pulls the cartilage clamped between the first clamping plate 4 and the second clamping plate 5, enables the left and right ends of the cartilage to be separated from the costal cartilage of the supply area, and accordingly local stripping of the costal cartilage of the supply area is completed. The barbed nail 8 can prevent the costal cartilage from slipping off from the splint, and is favorable for improving the success rate of the operation of stripping the costal cartilage. The cutting edge of the longitudinal cutter 6 is set to be a saw-toothed shape so as to greatly reduce the resistance when the longitudinal cutter cuts costal cartilage and enable the longitudinal cutter 6 to easily penetrate through, the longitudinal cutter 6 is connected with the first clamping plate 4 through a bolt 7, and the cutting edge of the longitudinal cutter 6 can be replaced after being worn. The utility model discloses the 6 perpendicular to pincers bodies of longitudinal knife that set up is on a parallel with and supplies district costal cartilage and main rib nerve when the operation, does not set up with costal cartilage and the neural vertically cutter of rib, and this structure is when peeling off costal cartilage and looking for the cutting position, but the unexpected fish tail of the biggest reduction cutter, the unexpected condition that cuts off the rib nerve. The utility model discloses can peel off one section costal cartilage of appropriate width from whole root costal cartilage as required, make and supply district costal cartilage to remain partial transverse connection, effectively shorten the healing time that supplies the district surface of a wound, and keep the support to all around costal nerves, alleviate the postoperative and to the neural damage of rib, when shelling out costal cartilage, the incision that does not have complete crosscut on the costal cartilage is favorable to avoiding the neural position of rib, realize complete the reservation to rib nerve, reduction operation wound that can be by a wide margin.

At present costal cartilage's usage mainly used ear, the traumatic defect of nose repair, rebuild and cosmetic plastic, the size of longitudinal knife 6 can come nimble setting according to actual use, and wherein preferred size is: the width of the longitudinal cutter 6 is 1cm-1.7cm, and the length of the longitudinal cutter 6 is 2.5cm-4 cm. When the size is selected, the obtained costal cartilage can meet the majority of use requirements of teenagers and adults, and a proper supply area is easy to find.

The utility model discloses a make the costal cartilage that presss from both sides between first splint 4 and the second splint 5 change after the rip cutting in breaking away, can adopt following structure: the surfaces of the first clamping plate 4 and the second clamping plate 5 which face each other are concave cambered surfaces, the thickness of the two ends of the first clamping plate 4 and the second clamping plate 5 in the length direction is larger than that of the middle part, and the difference between the two ends of the first clamping plate 4 and the second clamping plate 5 in the length direction and the thickness of the middle part is 0.5-1 mm. This structure can exert bigger pressure at rib cartilage both ends when first splint 4 and 5 centre gripping rib cartilages of second splint, makes its break away to can ensure that

first splint

4 and 5 length direction both ends of second splint can not form sharp cutting part, avoid causing the damage to rib nerve when searching cutting position in-process accidental contact rib nerve.

The utility model discloses a resistance when further reducing slitting knife 6 and running through can with slitting knife 6 is close to the face processing of articulated shaft 3 and is the arcwall face, and the centre of a circle of this arc place circle is located articulated shaft 3's axial direction line. This configuration is advantageous in eliminating the lateral resistance created by the slitting knife 6 as it cuts into the costal cartilage due to the change in the angle of cut.

The utility model discloses for the convenience of main sword doctor selects suitable confession district and rip cutting position according to costal cartilage's density during operation, can second splint 5 is close to first splint 4 one side and sets up recess 9 on the surface, installation LED lamp pearl 10 in the recess 9, and recess 9 surface covering has printing opacity apron 13, and second pincers body 2 is gone up and is installed battery case 11, sets up switch 12 on the battery case 11, and battery case 11 and switch 12 pass through supply circuit and are connected with LED lamp pearl 10. After a power supply circuit between the battery box 11 and the switch 12 and the LED lamp beads 10 is conducted, the LED lamp beads 10 form a light source on the second clamping plate 5, and when the second clamping plate 5 extends into the rear part of the costal cartilage, a leading doctor can judge the density of the costal cartilage and clearly observe the trend of peripheral fascia and costal nerves according to the light transmission condition of the costal cartilage, so that convenience is created for correctly selecting a proper supply area and a proper longitudinal cutting position. The power supply circuit can be packaged and fixed on the surface of the second clamp body 2 by adopting a waterproof sleeve, and a copper circuit can be embedded in the second clamp body 2 by a metal etching technology and sealed.
