A channel 101-1 is provided on the transparent observation window 101 for conveniently passing surgical tools, and a strap 101-2 is provided at the outer end of the channel 101-1.

[0034] In this embodiment, the biosafety protection device 1 further includes a head seat 106 for supporting the dog's head, and a bracket 107 is provided on the top surface of the head seat 106 .

[0035] like Figure 3 As shown, the bottom of the support frame 105 is connected to the head seat 106. Specifically, a mounting hole 108 is provided at the bottom of the support frame 105, and a threaded hole 109 is provided on the side wall of the head seat 106. The mounting hole 108 is fixed to the threaded hole 109 by a hand-tightening bolt 110.

[0036] like Figure 4 As shown, a connector 3 is provided at the edge of the transparent observation window 101 at a position corresponding to the support frame 105, and the connector 3 is clamped with the top of the support frame 105. The connector 3 includes a long connector 301, one end of which is connected to the transparent observation window 101, and the other end is provided with an anti-slip blocker 302; a slot 303 is provided at the top of the support frame 105, and the long connector 301 is placed in the slot 303, and the anti-slip blocker 302 is against the outer wall of the support frame 105.

[0037] like Figure 5 and 6 As shown, the sampler 2 includes a sampling tube 201 , a front end of the sampling tube 201 is provided with a serrated blade 202 , and a rear end of the sampling tube 201 is plugged with a sealing cap 203 .

[0038] In this embodiment, a narrow slit opening 204 is provided on the outer wall of the front end of the sampling tube 201; a wire guide hole 205 is provided in the outer wall of the sampling tube 201, the upper end of the wire guide hole 205 extends to the upper end of the sampling tube 201, and the lower end of the wire guide hole 205 extends to the narrow slit opening 204. Multiple groups of limiting pieces are provided in the narrow slit opening 204, and each group of limiting pieces includes two offset and stacked spring pieces 207, the upper spring piece 207 is fixed to the upper edge of the narrow slit opening 204, and the lower spring piece 207 is fixed to the lower edge of the narrow slit opening 204. A cutting wire 206 is provided on the outer side of the spring piece 207, one end of the cutting wire 206 is fixed to one end of the narrow slit opening 204, and the other end passes through the wire guide hole 205 and extends to the upper end of the sampling tube 201.

[0039] like Figure 7 As shown, the use process of the present invention is as follows:

[0040] First, the flexible protective cover 104 is placed on the dog's head through the hole 104-1, and then the dog's head is placed in the bracket 107 on the top surface of the head seat 106, and then the support frame 105 is installed on the threaded hole 109 through the hand-tightened bolts 110, and then the connectors 3 around the transparent observation window 101 are clamped in the clamping groove 303 on the top of the support frame 105, so that the transparent observation window 101 is supported. After the operator puts on the rubber protective gloves 103, the operation can be performed on the dog's head, wherein a channel 101-1 is set on the transparent observation window 101 for convenient transmission of surgical tools. It should be noted that the craniotomy tools used are generally skull drills and craniotomy saws.

[0041] After the craniotomy of the dog, the sampling tube 201 is lightly pressed and rotated to move it downward, and the blade 202 is convenient for cutting the brain tissue during the rotation. After the target brain tissue enters the sampling tube 201, the cutting wire 206 at the upper end of the sampling tube 201 is pulled, and the cutting wire 206 passes over two spring pieces 207 and enters the interior of the sampling tube 201. At this time, the sampling tube 201 is rotated again, and the cutting wire 206 can cut off the connection between the tissue in the sampling tube 201 and the tissue below. Finally, the sealing cap 203 is covered on the rear end of the sampling tube 201, and the sampling tube 201 is pulled out as a whole to achieve the sampling of brain tissue.

[0042] The transparent observation window 101, the flexible protective cover 104 and the rubber protective gloves 103 are connected together as an integral structure and are disposable consumables. The sampler 2 is made of stainless steel and can be used multiple times after being sterilized.

Specifically, a bracket 107 is provided on the top surface of the head seat 106, and the dog's head is placed in the bracket 107. Two symmetrically arranged clamps 4 are provided in the bracket 107. The two clamps 4 can clamp the dog's head stably. The back of the clamps 4 are rotatably connected with an operating handle 401. The operating handle 401 has a thread. The operating handle 401 is threaded with the reserved handle mounting hole on the head seat 106. The optional operation of the operating handle 401 can drive the clamp 4 to move. The remaining structures in this embodiment are the same as those in the first embodiment.
