[0002] Surgical drills usually use the unidirectional rotation of the cutter head to grind bone tissue. The unidirectional rotation makes the instantaneous grinding amount of the cutter head to the bone tissue larger, the wound surface is larger, and the recovery of bone tissue is slower; , the commonly used surgical drill has a single effect, and the grinding effect on complex bone tissue is not good

Embodiment 1
[0025] Depend on figure 1 , figure 2 , Figure 5 and Figure 6 As shown, first pass the grinding handle connected to the grinding head 1 through the support rod 2 to expose the grinding head 1, then hold the operating handle 22, press the control button 21 to squeeze the corresponding spring 42 inward, and at the same time, Because the strip groove 44 is a stepped structure with a transition slope 43 that is high inside and low outside, and one end of the latch 41 is provided with a section of flat square bar that matches the shape of the strip groove 44, the flat The square rod is passed through the bar-shaped groove 44, and the step end face of the upper end of the flat square rod is abutted against and slid with the end face of the step-shaped flat structure on the control button 21, so that when the bar-shaped groove 44 moves inward, the step-shaped flat structure The upper end surface of the upper end slides against the step end surface of the upper end of the flat ro...
Embodiment 2
[0029] Such as figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the difference from Embodiment 1 is that the central axis of the grinding handle is parallel to the central axis of the support rod 2 and is set eccentrically, that is, a reciprocating device and a limit device are used on the medical eccentric grinding drill. On the basis of the medical eccentric grinder, the operating space is increased and the use is more convenient.
Embodiment 3
[0031] Such as figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, the difference from Embodiment 1 is that a support ring 3 is provided on the support rod 2, and the support ring 3 is sleeved on the outer surface of the support rod 2. In the last auxiliary pipe (not shown), the support ring 3 moves in the auxiliary pipe, and at the same time, the operating handle 22 is oscillated to grind the relevant surgical grinding parts.
[0032] In addition, in the above three embodiments, when the surgical site needs to be ground, the cylindrical grinding head 1 with diamond sand on the front end and the peripheral surface can be selected.

Abstract
The invention discloses an abrasive drill for an operation. The abrasive drill comprises an abrasive drill device and a reciprocating device. The abrasive drill device comprises an abrasive tip (1) and a supporting rod (2). The abrasive tip (1) is arranged inside the supporting rod (2) in a penetrating mode through an abrasive handle. One end of the reciprocating device is connected with the abrasive handle, and the other end of the reciprocating device is connected to a driving device. The reciprocating device drives the abrasive drill device under the drive of the driving device to perform the reciprocating rotation motion. Due to the reciprocating device connected to the abrasive handle, on the various using conditions, the rotating abrasive tip is driven to perform reciprocating bone tissue grinding operation, and the abrasive drill is simple in structure, convenient and rapid to operate, high in stability and good in safety.
Description
technical field [0001] The invention relates to the technical field of bone tissue grinding tools, in particular to a surgical drill. Background technique [0002] Surgical drills usually use the unidirectional rotation of the cutter head to grind bone tissue. The unidirectional rotation makes the instantaneous grinding amount of the cutter head to the bone tissue larger, the wound surface is larger, and the recovery of bone tissue is slower; , the commonly used surgical burr has a single use effect, and the grinding effect on complex bone tissue is not good. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a surgical burr that can effectively control the grinding amount and improve the grinding quality. [0004] Technical scheme of the present invention is as follows: [0005] A surgical burr, comprising a burr device and a reciprocating device, the burr device includes a grinding head and a support rod, the gr...
