[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] As shown in the attached Figure 1 、attached Figure 2 and attached Figure 3 figures, a cell cryopreservation and resuscitation transfer forceps includes a first pliers rod 1 and a second pliers rod 2, and the middle parts of the first pliers rod 1 and the second pliers rod 2 are rotatably connected;
[0022] On the opposite sides of the lower ends of the first clamping rod 1 and the second clamping rod 2, arc-shaped clamping jaws 6 are respectively installed, and a plurality of groups of tooth-shaped protrusions 7 are arranged on the inner sides of the arc-shaped clamping jaws 6;
[0023] A braking member 8 is installed on the upper part of the first clamping rod 1. On the side of the braking member 8 close to the second clamping rod 2, a plurality of groups of first braking racks 9 are arranged. A groove body 10 into which the braking member 8 is inserted for cooperation is installed on the upper part of the second clamping rod 2. A moving plate 11 is arranged inside the groove body 10. On the side of the moving plate 11 close to the first clamping rod 1, a plurality of groups of second braking racks 12 are installed.
[0024] With the above structure, the top of the clamping part of the transfer forceps is designed as the arc-shaped clamping jaws 6 with a plurality of groups of tooth-shaped protrusions 7, so that when freezing or thawing and transferring cells, the two arc-shaped clamping jaws 6 can more effectively clamp the cell cryopreservation tube, making it difficult for the cell cryopreservation tube to fall off;
[0025] After clamping the cell cryopreservation tube, the braking member 8 is inserted into the inside of the groove body 10, and the first braking rack 9 engages with the second braking rack 12, so that when the transfer forceps clamp the cryopreservation tube, it saves the hand force and reduces fatigue. The specific structure is as follows:
[0026] Combined with the attached Figure 3 and the attached Figure 4 As shown, two positioning rods 14 are installed on the side of the moving plate 11 away from the second braking rack 12. The two positioning rods 14 respectively slide through the bottom of the groove body 10 and a push plate 13 is connected between them. Two springs 15 are connected between the push plate 13 and the bottom of the groove body 10, and the springs 15 are sleeved on the outer sides of the positioning rods 14.
[0027] With the above structure, when the first braking rack 9 engages with the second braking rack 12, the moving plate 11 is extruded towards the bottom of the groove body 10, so that the positioning rods 14 slide on the bottom of the groove body 10, and the push plate 13 pulls the springs 15 to expand. The first braking rack 9 is engaged with the second braking rack 12 by the resilience of the springs 15. When the transfer forceps transfer the cryopreservation tube to the designated position, the push plate 13 is pulled in the direction away from the groove body 10, and the first braking rack 9 and the second braking rack 12 move away from each other, releasing the limit on the first braking rack 9, so that the first clamping rod 1 and the second clamping rod 2 can rotate, and the cryopreservation tube is taken out from the arc-shaped clamping jaws 6.
[0028] Combined with the attached Figure 1 As shown, a first clamping arm 3 is installed at the upper end of the first clamping rod 1, and the first clamping arm is a ring-shaped clamping handle.
[0029] An arc-shaped clamping handle 5 is installed at the upper end of the second clamping rod 2, and a second clamping arm 4 is installed on the arc-shaped clamping handle 5. The second clamping arm is an oval structure.
[0030] With the above structure, the first clamping arm 3 is designed as a circular clamping handle for convenient operation by the thumb, and the second clamping arm 4 is an oval structure that cooperates with the arc-shaped clamping handle 5 to facilitate the coordinated cooperation of the other four fingers and the thumb, making the hand more comfortable during operation.
