Description

Technical Field

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

[0002] In the process of treating patients, it is sometimes necessary to remove the rotten flesh in the wound. In the prior art, doctors usually 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 generated 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 electric 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 electric cutting device.

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

[0005] A medical electric cutting device comprises a cutting head, a transmission rod and a driver which are connected in sequence from far to near, wherein the driver drives the cutting head to rotate via the transmission rod; and a shell covering the above three, wherein the distal end of the shell is opened and the cutting head is exposed therefrom; and also comprises two catheters, wherein one of the catheters sprays liquid into a wound and the other catheter sucks liquid out of the wound.

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

[0007] The shell is divided into a front section covering the cutter head, a middle section covering the transmission rod and a rear section covering the driver from far to near; the front section and the middle section are double-layer structures, one catheter penetrates through the middle section and is connected with its inner core, and another catheter penetrates through the middle section and is connected with its interlayer.

[0008] The shell is divided into a front section covering the cutter head, a middle section covering the transmission rod and a rear section covering the driver from far to near; a cover shell is sleeved on the middle section, and the cover shell can be buckled around the wound to form a closed space.

[0009] The cover shell is hinged to the middle section.

[0010] The cover shell and the middle section are detachably connected.

[0011] The cover shell is transparent.

[0012] A plurality of through holes are formed on the cover shell.

[0013] A camera is detachably mounted on the through hole.

[0014] A handle is detachably mounted on the through hole.

[0015] A protective cover is detachably mounted on the distal end opening of the shell, and a plurality of through holes are formed on the protective cover for allowing rotten meat to pass through so as to be cut by the knife head.

[0016] Compared with the prior art, the advantages of the utility model are:

[0017] When powered on, the driver can drive the cutter head to rotate via the transmission rod, and the rotating cutter head cuts the rotten flesh and breaks it. At the same time, a catheter continuously sprays liquid (which can be saline) into the wound, and the liquid continuously flushes the wound to separate the cut and peeled rotten flesh from the wound and dilute the blood. Synchronously, another catheter probes into the wound and continuously sucks outward, so that the liquid can be discharged from the wound along with the broken rotten flesh. By setting up a catheter, the blood can be diluted in time during the debridement process and discharged from the wound along with the broken rotten flesh, thereby effectively avoiding visual interference caused by blood accumulation. In addition, the liquid flushed out of the catheter can separate the cut and peeled rotten flesh from the wound, thereby effectively reducing residue. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Example

[0026] like Figures 1 to 5 As shown, the medical electric cutting device of this embodiment includes a cutter head 1, a transmission rod 2 and a driver 3 connected in sequence from far to near, and the driver 3 drives the cutter head 1 to rotate through the transmission rod 2; and a shell 4 covering the above three, the distal end of the shell 4 is opened, and the cutter head 1 is exposed; and also includes two catheters 5, one of which sprays liquid to the wound, and the other catheter 5 sucks out from the wound. The connection between the cutter head 1 and the transmission rod 2, the connection between the transmission rod 2 and the driver 3, and the connection between the driver 3 and the external power supply are all prior art, and one catheter 5 is connected to an external pump and the other catheter 5 is connected to an external negative pressure device to achieve the function of spraying liquid and sucking, which are also prior art. In the power-on state, the driver 3 can drive the cutter head 1 to rotate through the transmission rod 2, and the rotating cutter head 1 cuts the rotten meat and breaks it. At the same time, a catheter 5 continuously sprays liquid (which can be physiological saline) to the wound, and the liquid continuously rinses the wound to separate the rotten meat that has been cut and peeled from the wound and dilutes the blood. At the same time, another catheter 5 is inserted into the wound and continuously sucked outward, so that the liquid can be discharged from the wound along with the broken rotten flesh. By setting up the catheter 5, the blood can be diluted in time during the debridement process and discharged from the wound along with the broken rotten flesh, thereby effectively avoiding the visual interference caused by blood accumulation. In addition, the liquid flushed out of the catheter 5 can separate the cut and peeled rotten flesh from the wound, thereby effectively reducing the residue.

[0027] In this embodiment, the outer shell 4 is divided into a front section 41 covering the cutter head 1, a middle section 42 covering the transmission rod 2, and a rear section 43 covering the driver 3 from far to near; the front section 41 and the middle section 42 are double-layered, one catheter 5 penetrates through the middle section 42 and is connected to the inner core 44, and another catheter 5 penetrates through the middle section 42 and is connected to the interlayer 45. The front ends of the inner core 44 and the interlayer 45 are both open, one catheter 5 is connected to the inner core 44, and the liquid ejected from the catheter 5 enters the inner core 44 and is ejected from the front opening toward the wound; the other catheter 5 is connected to the interlayer 45, and the front opening of the interlayer 45 penetrates into the wound. Under the suction action of the catheter 5, the liquid entrained with the broken rotten meat enters the interlayer 45 and flows toward the catheter 5, and is finally discharged from the catheter 5. By setting the front section 41 and the middle section 42 into a double-layer structure, two independent channels, the inner core 44 and the interlayer 45, are formed. The two channels can be connected to a conduit 5 respectively, so that two independent spaces for injecting liquid and sucking liquid are formed in the outer shell 4, thereby preventing the clean liquid from mixing with the liquid containing broken meat and blood. Of course, in other embodiments, the conduit 5 for injecting liquid and the conduit 5 for sucking liquid can also be switched.

[0028] In this embodiment, the shell 4 is divided from far to near into a front section 41 covering the cutter head 1, a middle section 42 covering the transmission rod 2, and a rear section 43 covering the driver 3; the middle section 42 is provided with a cover shell 6, which can be buckled around the wound to form a closed space. Specifically, the cover shell 6 is hinged with the middle section 42. The cover shell 6 and the middle section 42 are detachably connected. The cover shell 6 is transparent. The flow rates of the two catheters 5 are basically consistent. By setting the cover shell 6, a closed space can be formed when it is buckled around the wound, thereby avoiding the liquid from rushing into the wound from the catheter 5, and the meat scraps and liquid splashing around to pollute the surrounding environment when the cutter head cuts rotten meat. At the same time, in order to facilitate operation, the cover shell 6 and the middle section 42 are arranged in a hinged form, and the doctor can rotate the shell 4 with the cover shell 6 fixed, so as to control the movement of the cutter head 1 in the wound. At the same time, since the sizes of the wounds of different patients are different, the cover shell 6 and the middle section 42 are set to a detachable connection form, so that the cover shell 6 of different sizes and models can be selected according to the size of the wound to adapt to the size of the wound. In addition, in order to facilitate the understanding of the cutting situation in the wound, the cover shell 6 is set to be transparent, and the doctor can observe through the cover shell 6. In other embodiments, a plurality of through holes 61 can also be formed on the cover shell 6, and a camera 7 can be detachably installed on the through hole 61, and the doctor can observe the situation in the wound through the camera 7. Further, the camera 7 and the through hole 61 are hinged with an iris mechanism (which is the existing technology), so as to facilitate the disassembly and movement of the camera 7 with one hand. In addition, a handle 8 is detachably installed on the through hole 61. During the operation, the doctor can hold the handle 8 with one hand to control the cover shell 6 to stably cover the wound, and operate the camera 7 and the cutter head 1 with the other hand.

[0029] In this embodiment, a protective cover 9 is detachably mounted on the distal opening of the housing 4, and a plurality of holes are formed on the protective cover 9 for the rotten meat to pass through so as to be cut by the cutter head 1. During operation, the doctor pushes the protective cover 9 to make it close to the rotten meat to be cut. Under the action of pressure, the rotten meat passes through the hole from the outside and protrudes a certain height on the inside. At this time, the cutter head is close to the inside of the protective cover 9 and rotates at high speed to cut off the protruding rotten meat. By providing the protective cover 9, it is possible to effectively avoid the cutter head 1 from being completely exposed and causing excessive cutting. In addition, the shape of the protective cover 9 is adapted to the shape of the cutter head 1. The cutter head 1 can be arranged in a plane, spherical, cylindrical, truncated cone, conical, etc., so as to better adapt to wounds of different shapes.
