Medical manual cutting device

Abstract

The utility model discloses a medical manual cutting device which comprises a cutter head and a cutter handle connected with the cutter head. The edge of the tool bit is sharp; a first channel and a second channel which are independent of each other are formed in the knife handle, the first channel is used for spraying liquid to a wound, and the second channel is used for outward suction from the wound. By arranging the first channel and the second channel, blood can be diluted in time in the debridement process and discharged from a wound along with broken rotten meat, and therefore sight line interference caused by blood accumulation can be effectively avoided. In addition, the liquid rushed out of the first channel can enable the cut and stripped rotten meat to be separated from the wound, and therefore residues are effectively reduced.

Description

Technical Field

[0001] The utility model mainly relates to the technical field of medical instruments, in particular to a medical manual cutting device. Background Art

[0002] In the process of treating patients, it is sometimes necessary to remove the rotten flesh in the wound. Due to the lack of a dedicated cutting device, doctors can usually only use a scalpel to cut the rotten flesh, and then remove the cut and separated pieces of meat from the wound. This method of using a scalpel to cut and remove rotten flesh has two disadvantages: first, the wound will bleed during the cutting process, and the blood accumulated in the wound will seriously affect the doctor's vision, thereby affecting the doctor's ability to distinguish which parts are the rotten flesh that needs to be removed; second, the debris produced by the scalpel cutting is scattered in the wound, and its volume is small and difficult to be accurately distinguished, so it is difficult to be cleaned up and easily causes residue. Therefore, there is a need for a medical manual cutting device that can remove blood and debris in time during surgery. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a medical manual cutting device.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A medical manual cutting device comprises a blade head and a blade handle connected thereto; the blade head has a sharp edge; the blade handle is formed with a mutually independent channel 1 and channel 2, the channel 1 is used to spray liquid to a wound, and the channel 2 is used to suck liquid out of the wound.

[0006] As a further improvement of the above technical solution:

[0007] The cutter head is in an arc-shaped shell structure.

[0008] The cutter head is of sandwich structure, the inner cavity of the cutter head is connected with the channel, and the inner wall of the cutter head is formed with a plurality of openings.

[0009] The cutter head is of a sandwich structure, the inner cavity of which is connected with the second channel, and the inner wall of which is formed with a plurality of openings.

[0010] The proximal end of the channel 1 faces the inner wall.

[0011] The knife handle is in a prism shape, and its small end is connected to the knife head.

[0012] The cutting device also includes pump 1 and pump 2. Pump 1 is connected to the distal end of channel 1 and is used to pump liquid into channel 1. Pump 2 is connected to the distal end of channel 2 and is used to provide negative pressure to channel 2.

[0013] Compared with the prior art, the advantages of the utility model are:

[0014] By setting a blade with a sharp edge, the operator can hold the blade handle connected to it to control the blade to cut the rotten meat in the wound. At the same time, by setting channel one and channel two in the blade handle, channel one is used to continuously spray liquid into the wound. The liquid continuously flushes the wound to separate the rotten meat that has been cut and peeled from the wound and dilutes the blood. Simultaneously, channel two probes into the wound and continuously sucks outward, so that the liquid can be discharged from the wound along with the broken rotten meat. By setting channel one and channel two, the blood can be diluted in time during the debridement process and discharged from the wound along with the broken rotten meat, thereby effectively avoiding visual interference caused by blood accumulation. In addition, the liquid flushed out of channel one can separate the rotten meat that has been cut and peeled from the wound, thereby effectively reducing residue. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Example

[0022] like Figures 1 to 4As shown, the medical manual cutting device of this embodiment includes a blade head 1 and a blade handle 2 connected thereto; the blade head 1 has a sharp edge; the blade handle 2 is formed with a mutually independent channel 1 21 and channel 2 22, the channel 1 21 is used to spray liquid into the wound, and the channel 2 22 is used to suck out from the wound. By setting the blade head 1 with a sharp edge, the operator can hold the blade handle 2 connected thereto to control the blade head 1 to cut the rotten meat in the wound. At the same time, by setting the channel 1 21 and the channel 2 22 in the blade handle 2, the channel 1 21 is used to continuously spray liquid (which can be saline) into the wound, and the liquid continuously rinses the wound to separate the rotten meat that has been cut and peeled from the wound and dilute the blood. Simultaneously, the channel 2 22 probes into the wound and continuously sucks outward, so that the liquid can be discharged from the wound with the broken rotten meat. By setting the channel 1 21 and the channel 2 22, the blood can be diluted in time during the debridement process and discharged from the wound along with the broken rotten meat, thereby effectively avoiding the visual interference caused by blood accumulation. Furthermore, the liquid flushed out of the channel 1 21 can separate the cut and peeled rotten meat from the wound, thereby effectively reducing the residue.

[0023] In this embodiment, the blade head 1 is an arc-shaped shell structure. Specifically, the shape of the blade head 1 is similar to a spoon, and its edge can be used to cut rotten meat.

[0024] In this embodiment, the cutter head 1 is a sandwich structure, and its inner cavity 11 is connected to the second channel 22, and its inner side wall 12 is formed with a plurality of openings 13. Since the cutter head 1 is an arc-shaped shell structure, the minced meat cut off by the edge of the cutter head 1 generally remains on the inner side wall 12 of the cutter head 1. By setting the cutter head 1 as a sandwich structure, and connecting its inner cavity 11 to the second channel 22, and opening a plurality of openings 13 on the inner side wall 12 of the cutter head 1, the liquid mixed with the broken rotten meat and blood can pass through the openings 13 and the inner cavity 11 into the second channel 22 and be discharged. At the same time, the proximal end of the first channel 21 is directly opposite to the inner side wall 12. The liquid can be directly sprayed onto the inner side wall 12, thereby flushing away the rotten meat attached to its surface. In other embodiments, the inner cavity 11 can also be connected to the first channel 21.

[0025] In this embodiment, the knife handle 2 is in a prism shape, and its small end 23 is connected to the knife head 1. By setting the knife handle 2 in a prism shape, it can better fit the palm of the operator, thereby improving the convenience of operation.

[0026] In this embodiment, the cutting device further includes a pump 1 3 and a pump 2 4, wherein the pump 1 3 is connected to the distal end of the channel 1 21 and is used to pump liquid into the channel 1 21; the pump 2 4 is connected to the distal end of the channel 2 22 and is used to provide negative pressure to the channel 2 22. In order to achieve the functions of pumping liquid and suction, the cutting device is further provided with a pump 1 3 and a pump 2 4, wherein the pump 1 3 is connected to the distal end of the channel 1 21 and is used to pump liquid into the channel 1 21; the pump 2 4 is connected to the distal end of the channel 2 22 and is used to provide negative pressure to the channel 2 22. It should be noted that the pump used in this embodiment is a commercially available product, and its structure and working principle are not described in detail here.
