Example 1

Referring to FIGS. 1 to 3 , the present embodiment provides a surgical peeling knife 10 , which includes a knife handle 11 , a knife head 13 and a spray device 15 .

Optionally, the handle 11 in this embodiment is preferably a cylindrical handle, and the handle 11 in this shape is more suitable for hand-holding than other shapes, and the degree of tightness can be easily controlled.

The handle 11 has opposite first ends 111 and second ends 113 , wherein the first end 111 is used to connect the tool head 13 .

The knife handle 11 is provided with a chute 115 extending through the first end 111 along the direction from the first end 111 to the second end 113 , and the cutter head 13 is slidably connected to the chute 115 . That is, the cutter head 13 can extend into or out of the first end 111 of the handle 11 by sliding in the sliding groove 115 .

The cutter head 13 includes a cutter head body 131 and a cutter bar 133 . One end of the cutter head body 131 is detachably connected to the cutter bar 133 , and the cutter bar 133 is slidably connected to the chute 115 .

Further, the inside of the knife handle 11 is also provided with a receiving cavity 117 parallel to the sliding groove 115 , and the end face of the first end 111 is provided with a first socket 118 communicating with the receiving cavity 117 , and the first socket 118 is used for inserting the knife head body 131 Inserted into the accommodating cavity 117 in a non-use state.

When the surgical peeling knife 10 does not need to be used, the cutter head body 131 can be removed from the cutter bar 133, and then the cutter head body 131 can be inserted into the first socket 118 in reverse, that is, the cutting edge side of the cutter head body 131 can pass through the first socket 118. A socket 118 is inserted into the accommodating cavity 117 of the knife handle 11 to prevent the knife head body 131 from accidentally hurting others. When the surgical peeling knife 10 needs to be used, the knife head body 131 is taken out from the first socket 118 , and then connected to the knife bar 133 to adjust the sliding distance of the knife bar 133 in the chute 115 , thereby adjusting the position of the entire knife head 13 , until it reaches the site to be operated on.

Optionally, the cutter head body 131 in this embodiment is provided with a magnifying glass 14 (as shown in FIG. 2 ), and the magnifying glass 14 is located on the side of the cutter head body 131 opposite to the cutter edge side. Optionally, the magnifying glass 14 is connected with a first connecting rod 141 and a second connecting rod 143 , and the first connecting rod 141 is detachably connected to the side of the cutter head body 131 opposite to the cutting edge side. One end of the second connecting rod 143 is movably connected to one end of the first connecting rod 141 away from the cutter head body 131 , and the other end is connected to the magnifying glass 14 . Optionally, one end of the second connecting rod 143 is movably connected to one end of the first connecting rod 141 away from the cutter head body 131 through a universal joint.

In view of the above structure, during use, the alignment angle of the magnifying glass 14 can be adjusted by adjusting the connection angle between the first connecting rod 141 and the second connecting rod 143, so as to realize an all-round magnified observation of the peeling part.

Further, in this embodiment, the outer wall of the handle 11 is further provided with a handle portion 119 , and the handle portion 119 is arranged along the direction from the first end 111 to the second end 113 of the handle 11 . The handle portion 119 includes four grooves 1191 for preventing finger movement. The above-mentioned four grooves 1191 are arranged along the same linear direction.

During use, the four fingers of the medical staff except the thumb can be respectively placed in the four grooves 1191 correspondingly. By arranging the groove 1191, the phenomenon of changing the force applied during the peeling process due to the sliding of fingers on the handle surface during the peeling process can be avoided.

Preferably, the surface of the groove 1191 is provided with an air-permeable layer (not shown in the figure), and the surface of the air-permeable layer is provided with an anti-skid pattern (not shown in the figure). By setting the breathable layer, the breathable function can be realized, and the sweating of the hands of medical staff during the peeling process can be reduced. By setting the anti-skid pattern, the friction force between the fingers and the groove 1191 can be increased, so as to prevent the hand of the medical staff from slipping.

Referring to FIGS. 1 , 3 and 4 together, the medicine spraying device 15 includes a medicine storage chamber 151 , a booster (not shown), a medicine delivery pipe 155 and a plurality of medicine spray holes 157 . The medicine delivery tube 155 is arranged in parallel with the chute 115 in the knife handle 11. One end of the medicine delivery tube 155 is communicated with the medicine storage cavity 151, and the other end extends to the end face of the first end 111. The end face of the end 111 is communicated with the drug delivery pipe 155 , and the booster is connected to the drug storage chamber 151 and used to apply positive pressure to the drug in the drug storage chamber 151 .

The above-mentioned medicine storage cavity 151 can be arranged outside the surgical peeling knife 10 or inside the handle.

Optionally, the number of drug delivery tubes 155 in this embodiment is preferably an even number, and the even number of drug delivery tubes 155 are evenly and symmetrically distributed on both sides of the chute 115 .

In other words, it can be understood that the chute 115 and the first socket 118 divide the end face of the first end 111 of the tool handle 11 into a first area 1111 and a second area 1113 on the left and right sides, wherein the first area 1111 is located in On the side of the first socket 118 away from the chute 115 , the second region 1113 is located on the side of the chute 115 away from the first socket 118 . A plurality of spray holes 157 are respectively arranged in the first area 1111 and the second area 1113, and the even-numbered medicine delivery pipes 155 are symmetrically divided into corresponding areas in the handle 11 corresponding to the above two areas on average and are connected with the spray holes. 157 Connected.

Before the operation and during the operation, a positive pressure can be applied to the medicine storage cavity 151 through the booster, so that the medicine in the medicine storage cavity 151 flows along the medicine delivery tube 155 to the first end 111 of the handle under the action of the positive pressure, and is sprayed by the spray. The medicine hole 157 is sprayed out.

Alternatively, the above-mentioned drug may be a disinfectant, or an analgesic, an anti-inflammatory drug, a hemostatic drug, and the like.

Preferably, each drug delivery tube 155 is provided with a one-way valve 1551 so that the drug in the drug storage cavity 151 flows out of the spray hole 157 in one direction. The one-way valve 1551 is preferably disposed at a position of the drug delivery tube 155 near the end face of the first end 111 of the handle to prevent blood or other soft tissues from entering the drug delivery tube 155 during the peeling process.
