Detailed Description

The invention is described in detail below with reference to the figures and the specific embodiments.

FIG. 1 is a schematic front view of a costal cartilage joint section dissector in accordance with example 1 of the present invention. As shown in fig. 1, the costal cartilage joint section dissection detacher of the embodiment comprises a rod body 1, a handle 2 and a dissection head 3. The handle 2 is connected at the one end of the body of rod 1, cuts and peels off head 3 and connects at the other end of the body of rod 1. The costal cartilage joint section dissector of the present invention may be made of a variety of materials, as long as it is sufficient to be suitable for surgical procedures. Preferably, it is made of medical stainless steel.

The shaft body 1 needs to have sufficient strength, and therefore the shaft body 1 in the preferred embodiment has an elongated cylindrical body.

The handle 2 may be provided in a variety of shapes and configurations, only to meet the requirements for a suitable grip.

In this embodiment, the handle 2 is provided with anti-slip threads 21. The anti-slip lines 21 can prevent the handle 2 from slipping off from the hand, are beneficial to being held by a doctor, can cut quickly and effectively, and can avoid damaging the knife edge tissue and the internal tissue in the cutting process.

Fig. 2 is a schematic view showing a reverse structure of the costal cartilage joint dissector in fig. 1. Fig. 3 is a side view of the costal cartilage joint dissection detacher in fig. 1. Fig. 4 is a partially enlarged view of a of fig. 3. Referring to fig. 1, 2, 3 and 4, the cutting and stripping head 3 includes two parts, the first part is a cutting part 31 located at the front end of the rod body 1. The second part is a peeling head 32, and the peeling head 32 is connected to the front end of the cutting part 31 and forms a certain included angle a with the cutting part 31.

In this embodiment, two cutting edges 311 are respectively arranged on two side edges of the incision portion 31, and the cutting edges 311 are arranged on two sides of the incision portion, so that the front and back hands can be used for bidirectional cutting, and a doctor can conveniently and quickly obtain required costal cartilage sheets.

In order to ensure that a sufficient width of the costal cartilage sheet is obtained and simultaneously ensure that other tissues of the human body are not accidentally injured, the length of the blade is 0.8-1.6cm, and preferably, the length of the blade is 1-1.5 cm. In this embodiment, the length of the blade is 1.2 cm.

In the invention, the included angle a is larger than 90 degrees. If the angle a is 90 degrees, the costal cartilage joint dissector of the present invention is caught by the rib and is difficult to move after the dissecting head 32 penetrates into the gap of the costal cartilage. If the angle is too large, the cut portion cannot be attached to the surface of the costal cartilage, and cutting is difficult. Therefore, the included angle a is preferably 100 degrees to 110 degrees, and in this embodiment, the included angle a is 104 degrees. The included angle a in the range is selected, so that the stripping head 32 can effectively go deep into the gap of the costal cartilage, the cutting is convenient, the clamping is avoided, the stripping head can quickly move along the extending direction of the costal cartilage, the cutting is carried out on the surface of the costal cartilage, and the required costal cartilage sheet is obtained.

In this embodiment, the shaft body 1, the handle 2 and the cutting and peeling head 3 are integrally formed. Adopt integrated into one piece technique, guarantee that whole costal cartilage joint portion cuts the surface of peeling off and be smooth, seamless, reduce the injury to the tissue, reduce the resistance simultaneously, realize quick effective cutting, shorten operation time, reduce the infection probability.

Specifically, the cutting and peeling head 3 is a sheet-like structure formed by extending the front end of the rod body 1, and the front end of the sheet is bent to form the peeling head 32. The sheet is bent to form the peeling head 32, and the peeling head 32 and the incision part 31 are in arc transition, so that other tissues of a human body cannot be damaged.

In order to further avoid the injury to the human body, the edges of the stripping head 32 and the cutting part 31 of the costal cartilage joint cutting stripper are provided with rounded corners, and the rounded corners can prevent edges of the cutting part 31 and the stripping head 32 from causing secondary injury to the human body.

In this embodiment, the thickness of the rod body 1 gradually increases from the front end to the rear end of the handle 2. In the invention, the stripping head 32 and the cutting part 31 are arranged into a sheet structure, and can be well inserted into the pores of costal cartilage for stripping and cutting; the thickness of the rod body 1 is gradually increased, so that the rib cartilage joint incising dissector provided by the invention has enough strength while the dissecting and cutting sensitivity is not influenced.

In order to achieve better cutting, the surface of the stripping head 32 bent to the incision part 31 in the present embodiment is a stripping surface 320, and the stripping surface 320 is a plane.

The surface of the cut portion 31 facing the peeling head 32 is a cut surface 310, and is also a flat surface. The two opposite curved surfaces of the stripping surface 320 and the incision surface 310 are direct contact surfaces of the costal cartilage joint, and the contact surfaces are smooth planes, so that the costal cartilage joint can be better attached to the costal cartilage joint, and stripping and cutting are facilitated.

Further for better realization of the joint, the rod body 1 extends upwards from the end connected with the cut-out portion 31 by a section, in which a side surface of the cylindrical rod body 1 is pressed flat to form a joint surface 11, and the joint surface 11 is also a plane and is located on the same plane with the cut-out surface 310. By adopting the arrangement, the rod body 1 which is a cylinder can be better attached to a human body, so that the cutting operation is convenient.

Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
