Embodiment 1

[0059] Such as Figure 1-3 As shown, a propelling mechanism of a cryotherapy apparatus includes: a housing 1, which is provided with an installation cavity 100 for the storage bottle 3 to be installed, that is, the housing 1 is hollow, and is used for cryotherapy. The internal parts of the instrument provide installation space; the tail of the housing 1 is provided with a communication hole 110 communicating with the installation cavity 100, and the inner wall of the housing 1 is provided with a first non-return structure 120 and an internal thread 130, and the The internal thread 130 is in the communication hole 110; the push knob 2 is movably arranged at the communication hole 110, and includes a resisting part 20, a connecting part 21 and a rotating part 22 connected in sequence, that is, the resisting part 20. The connecting part 21 and the rotating part 22 are integrated. For example, when the push knob 2 made of plastic is used, the pushing part 20, the connecting part 2...

Embodiment 2

[0068] Such as Figure 6-Figure 10 As shown, a cryotherapy instrument includes: the propulsion mechanism of the above-mentioned cryotherapy instrument; a flow storage bottle 3 is arranged in the installation cavity 100, and one end of the flow storage bottle 3 is connected to the pushing part 20 Offset, that is, the tail of the accumulator bottle 3 is in opposition to the thrust portion 20, and the mouth of the accumulator bottle 3 is at the end far away from the resist portion 20. In the accumulator bottle 3, such as nitrous oxide, carbon dioxide, etc. can be adorned. For cryotherapy, the storage bottle 3 can be a disposable packaged gas cylinder; the switch assembly 4 is arranged in the installation cavity 100 and includes a switch seat 40, a valve needle 41, a switch valve 42, and a reset shrapnel 43 and the injection pipe 44, the switch seat 40 is clamped in the housing 1, and the switch seat 40 is provided with a first flow channel 401; the valve needle 41 is arranged in ...

Abstract

The invention relates to the technical field of medical instruments, and discloses a propulsion mechanism of a cryotherapy apparatus and the cryotherapy apparatus. The propulsion mechanism comprises a shell and a propelling knob, wherein a mounting cavity for mounting a flow storage bottle is formed in the shell; a communicating hole communicated with the mounting cavity is formed in the tail of the shell; first non-return structures and an internal thread are arranged on the inner wall of the shell, and the internal thread is positioned in the communicating hole; the propelling knob is movably arranged at the communicating hole and comprises an abutting and pushing part, a connecting part and a rotating part which are connected in sequence; an external thread is arranged on the connecting part, and the external thread is connected with the internal thread; the abutting and pushing part is movably arranged in the mounting cavity in a penetrating mode, the abutting and pushing part can push the flow storage bottle to move forwards, the abutting and pushing part is provided with a plurality of second non-return structures in the circumferential direction of the abutting and pushing part, and the first non-return structures movably abut against the second non-return structures; and the rotating part protrudes out of the shell. The cryotherapy apparatus has the advantages of being small in size, convenient to use, high in safety performance and high in precision.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a propelling mechanism of a cryotherapy instrument and the cryotherapy instrument. Background technique [0002] Cryotherapy is a medical device that uses physical methods to destroy or excise human tissues by applying the low temperature generated by refrigerating substances and freezing devices, so as to achieve the purpose of treating diseases. At present, the cooling medium used in most hospitals is liquid nitrogen. [0003] When doctors in low-level hospitals use liquid nitrogen for cryotherapy, they first need to use stainless steel insulated containers to store a certain amount of liquid nitrogen at the hospital’s liquid nitrogen storage point, and then use medical cotton swabs to dip in liquid nitrogen and smear the patient’s body in need of treatment. The parts should be reapplied 2-3 times. When not in use for a long time, the liquid nitrogen must be disposed o...
