Description

Technical Field

[0001] The present invention relates to the technical field of surgical instruments, and in particular to a blood-suppressing surgical instrument for patients with surgical infections. Background Art

[0002] Surgical instruments mainly include surgical scalpels, which are special tools consisting of a blade and a handle used to cut human or animal tissue. They are an indispensable and important surgical tool in surgery. The blade usually has a cutting edge and a mounting groove for docking with the scalpel handle. The material is usually pure titanium, titanium alloy, stainless steel or carbon steel.

[0003] When a doctor holds a surgical scalpel to perform an operation, blood or tissue fluid will spread in the affected area. If the spread blood or fluid is not recovered and cleaned in time, it will affect the doctor's subsequent surgical operations. Therefore, it is necessary to clean up the blood or fluid in a short time after the blade cuts the affected area to facilitate subsequent surgical operations and ensure the efficient progress of the operation.

[0041] At the same time, the driving assembly also includes a movable seat 420, a first slide bar 370, a second slide bar 380, a second spring 390 and a third spring 410; the movable plate 430 is movably connected to the inner wall of the inner cavity 660 in the following structure: the first slide bar 370 and the second slide bar 380 are both connected to the inner wall of the inner cavity 660, the first slide bar 370 is parallel to the second slide bar 380, and the central axis of the first slide bar 370 is perpendicular to the central axis of the straw 180; the two sides of the movable seat 420 are movably sleeved on the first slide bar 370 and the second slide bar 380 respectively. Sliding rod 380; the second spring 390 is mounted on the first sliding rod 370; the third spring 410 is mounted on the second sliding rod 380; the second spring 390 and the third spring 410 are both in a compressed state, so that the movable seat 420 has a tendency to move toward the direction close to the first rack 240 (that is, in a normal state, the second rack 470 is engaged with the first rack 240); the movable plate 430 is slidably connected to the movable seat 420; the sliding direction of the movable plate 430 relative to the movable seat 420 is parallel to the length direction of the straw 180.

[0043] In addition, as attached Figure 1-3As shown, the drive assembly also includes a first positioning plate 350 and a second positioning plate 340; the second positioning plate 340 is connected to the inner wall of the inner cavity 660, the first positioning plate 350 is connected to the second positioning plate 340 (specifically, the first positioning plate 350 is connected to the second positioning plate 340 through the connecting arm 570), and the first positioning plate 350 and the second positioning plate 340 are coplanar; the first positioning plate 350 and the second positioning plate 340 are both parallel to the movable seat 420, and the first positioning plate 350 and the second positioning plate 340 are both located away from the movable plate 430. One side of the movable seat 420; the second positioning plate 340 is provided with a notch (unnumbered); the first positioning plate 350 is embedded in the notch, the first positioning plate 350 and the notch form an annular hole 360, and the connecting arm 570 spans the second waist hole 620; the annular hole 360 ​​includes a first waist hole 610, a second waist hole 620, a third waist hole 630 and a fourth waist hole 640; the first waist hole 610 is parallel to the second waist hole 620; the third waist hole 630 is parallel to the fourth waist hole 640; the extension direction of the first waist hole 610 is parallel to the length direction of the straw 180.

[0044] One end of the third waist hole 630 is connected to the end of the first waist hole 610 near the first end 130, and the other end of the third waist hole 630 is connected to the end of the second waist hole 620 near the first end 130; one end of the fourth waist hole 640 is connected to the end of the first waist hole 610 near the second end 140, and the other end of the fourth waist hole 640 is connected to the end of the second waist hole 620 near the second end 140; the second waist hole 620 is closer to the first end 130 than the first waist hole 610; the second waist hole 620 is located on the side of the first waist hole 610 away from the straw 180; the first slide post 550 is connected to the side of the movable plate 430 away from the movable seat 420; the first slide post 550 is movably arranged to pass through the annular hole 360; the first slide post 550 is perpendicular to the positioning plate; when the first slide post 550 is located in the first waist hole 610, the second rack 470 engages with the first rack 240.

[0045] When the first slide post 550 is moved in the annular hole 360, the first slide post 550 is restricted to slide in the first waist hole 610, and when the first slide post 550 is located in the first waist hole 610, the second rack 470 is engaged with the first rack 240. Therefore, in this process, the second rack 470 drives the first rack 240 to move in the direction close to the first end 130, thereby driving the straw 180 to extend out of the sleeve 190. After the first rack 470 is moved into the third waist hole 630, the movable plate 430 is forced to move away from the bellows 290, thereby separating the second rack 470 from the first rack 240. Then the first slide post 550 continues to move. After reaching the position closest to the first end 130, the pressing rod 280 can no longer be pressed. At this time, the pressing rod 280 is released. Under the action of the fourth spring 460, the first slide post 550 enters the second waist hole 620. Then, under the action of the second spring 390 and the third spring 410, the first slide post 550 enters the first waist hole 610; and the second rack 470 and the first rack 240 are engaged again, and the pressing rod 280 returns to its original position. At this time, it can be pressed again. By pressing the pressing rod 280 multiple times, the straw 180 can be fully extended from the sleeve 190 to facilitate the suction of blood or accumulated fluid.

[0046] At the same time, as attached Figure 2 and attached Figure 3 As shown, the drive assembly also includes a baffle rod 580 and a second baffle block 590; the baffle rod 580 is rotatably connected to the side of the first positioning plate 350 that faces away from the movable plate 430; the second baffle block 590 is connected to the side of the first positioning plate 350 that faces away from the movable plate 430; a torsion spring (not shown) is provided at the rotating shaft of the baffle rod 580, and the torsion spring causes the baffle rod 580 to abut against the second baffle block 590, and when the baffle rod 580 abuts against the second baffle block 590, the baffle rod 580 is parallel to the straw 180; the baffle rod 580 is used to allow the first slide column 550 to enter the second waist hole 620.

[0047] This arrangement can prevent the first slide column 550 from returning to the first waist hole 610 due to misoperation after entering the third waist hole 630, that is, ensure that the movement trajectory of the first slide column 550 is: first waist hole 610 → third waist hole 630 → second waist hole 620 → fourth waist hole 640 → first waist hole 610, and so on.
