The wall surface in portion 211.
Wherein, frozen pincers 20 are used as the medical apparatus melted, wherein pincers ontology 21 is the load for implementing ablation movement
Tool, specifically, when implementing ablation process to tissue to be treated, with clamp that ontology 21 is carried out by the movement of sliding the
Switching between one state and the second state, enable pincers ontology 21 in the first clamping jaw 211 and the second clamping jaw 212 put down
Movement that is sliding, stablizing, constantly carry out the tissue clamping, that is, when first state, the first clamping jaw 211 and the second clamping jaw
212 is close to each other to realize to the clamping of the pre- tissue for implementing ablation process, after the completion of processing to be ablated, switches to the second shape
State exits the tissue to clamp ontology 21.Wherein, ablation portion 22 and thermometric portion 23 are set on pincers ontology 21, specifically, are used for
The ablation portion 22 of ablation is located in the first clamping jaw 211, when clamping ontology 21 with first state clamping tissue, the first clamp
Portion 211 be close to tissue surface, therefore ablation portion 22 can effectively to the organizing and implementing ablation process, meanwhile, the thermometric for thermometric
Portion 23 also with the second clamping jaw 212 be close to tissue surface, in real time to the portion that is ablated to 22 melt tissue thermometric, due to ablation and
What thermometric worked in the state of clamping ontology 21 and clamping tissue, therefore, the efficiency of ablation and real-time, the accuracy of thermometric
It is guaranteed.
Further, in some embodiments, pincers ontology 21 further includes push rod 213 and elastic component, and push rod 213 is slidably
Ground and matrix 210 cooperate, and elastic component are provided between push rod 213 and the first clamping jaw 211, the other end of push rod 213 is exposed to
Outside matrix 210；Push rod 213 has under the action of elastic force so that the pincers ontology 21 in first state is converted to the second state
Trend.
Wherein, this is clamped with the sliding of push rod 213 plus the fit system of elastic force and matrix 210, the first clamping jaw 211, control
The conversion of the first state of body 21 and the second state, so that needing pincers ontology 21 being converted into first state in operator
When, push rod 213 is pushed, so that push rod 213 drives the first clamping jaw 211 close to the second clamping jaw 212.If desired maintain this first
State needs an external force to keep the positional relationship between the first clamping jaw 211 and the second clamping jaw 212.Meanwhile it if desired will pincers
When ontology 21 is converted into the second state, the elastic force between push rod 213 and matrix 210 is discharged, by elastic force, so that push rod
213 and the first clamping jaw 211 for being connect with push rod 213 slided on matrix 210, far from the second clamping jaw 212.

Pass through a groove of 215 resilient abutment of spring in the inner cavity of matrix 210), the other end of elastic button 214 is exposed to matrix
In the through-hole that 210 surfaces open up；
Push rod 213 offers sliding slot 80, and the peripheral wall of elastic button 214 offers the groove 81 being slidably matched with sliding slot 80,
When push rod 213 pushes the first clamping jaw 211 to the second clamping jaw 212 close to realize pincers ontology 21 to the converted of first state
When in journey, the push rod 213 of 214 relative motion of elastic button slides in the sliding slot 80 of push rod 213, and wherein push rod 213 is separate
One end of first clamping jaw 211 offers limit hole 82, and limit hole 82 is connected to sliding slot 80, when push rod 213 pushes the first clamping jaw
211 to the second clamping jaw 212 close to certain position when, elastic button 214 is close to the limit hole 82, due to elastic button 214
Ontology and matrix 210 between spring 215 (wherein, elastic button 214 has spring 215, as shown in Figure 6) work of elastic force
With so that elastic button 214 is sprung under the promotion of elastic force in limit hole 82, at this point, the peripheral wall of elastic button 214 is (non-recessed
81 position of slot) occur with push rod 213 against so that the relative position of elastic button 214 and push rod 213 in limit hole 82
It is fixed, while the elastic force of spring 216 (being detailed in Fig. 6) maintains the opposite position between the second clamping jaw 212 of the first clamping jaw 211
Relationship is set, so that pincers ontology 21 be allowed to remain first state, that is, stable clamp position.Conversely, as elastic button
214 pop up in limit hole 82, so that, elastic button 214 pops up in the through-hole that 210 surface of matrix opens up, and passes through spring 217
The elastic force of (see Fig. 6) acts on, so that the sliding slot 80 of the groove 81 of elastic button 214 and push rod 213 cooperates, in push rod 213 and base
Under resilient force between body 210, pincers ontology 21 is converted to the second state.
Wherein, by above-mentioned design, so that carrying out ablation operation in frozen pincers 20 or frozen pincers 20 being made to exit work
When, facilitate operator to operate, can simply carry out the conversion between pincers 21 first state of ontology and the second state, also,
