Embodiment Construction

[0021] a kind of like Figure 1-5 The special holder for cartilage trimming shown is composed of a handle and a disc-shaped contact surface. The handle is connected with the disc-shaped contact surface through a rotating shaft. The handle is composed of: gripping parts (3, 4), limiting reeds ( 5), a rotating shaft (6), and a front curved arm (7), and the disc-shaped contact surface is composed of a lower tray (1) and an upper cover plate (2).

[0022] The disc-shaped contact surface includes the lower tray (1) and the upper cover (2), ensuring the stability of the clamped object.

[0023] The handle includes a rotating shaft (6) and a front curved arm (7), so that the lower tray remains parallel to the upper cover. The handle also includes a limit spring (5), which makes the holder open when there is no external force.

Abstract

The invention relates to a clamp holder for trimming cartilage, which is used for trimming the cartilage during ear-nose-throat department surgery. The clamp holder consists of a handle and disc-like contact surfaces, wherein the handle is connected with the disc-like contact surfaces through a rotating shaft, and comprises holding parts and a reed; the holding parts are used for adjusting the space between the disc-like contact surfaces through the rotating shaft; and the disc-like contact surfaces are contacted with the cartilage to be trimmed through a lower pallet and an upper cover plate. By the clamp holder, the problem of low operation stability in the prior art is solved. A surgeon can trim the cartilage at various angles, so that the clamp holder is easy and convenient to operateand saves time.

Description

technical field [0001] The invention relates to a medical surgical instrument, in particular to a holder. In particular, the utility model relates to a cartilage trimming holder for trimming cartilage during ENT surgery. Background technique [0002] Tympanoplasty is an effective treatment for conductive deafness, and autologous cartilage is a commonly used material for tympanic membrane repair and ossicular chain reconstruction. In order to adapt to individual conditions, the cartilage taken from the tragus or the concha cavity needs to be trimmed. At present, medical institutions use toothed forceps to hold the cartilage during the operation, and use a scalpel to trim the cartilage. This method makes it difficult to hold the cartilage sheet stably for thinning and shaping. The operation is difficult and the success rate is low. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the existing cartilage pruning op...
