Abstract
The utility model relates to an adjustable puncture type cryoprobe for disease areas, which comprises a hollow cryoprobe rod with a tapered front end. The front part of the cryoprobe rod is a refrigerating area, a regulating sleeve rod which is shorter than the cryoprobe rod is sheathed with the cryoprobe rod in the position which is positioned at the front part of a hand-held sleeve rod, and the hand-held sleeve rod is arranged at the back of the cryoprobe rod; an input tube and a discharge tube for refrigerating gases are arranged at the back end of the cryoprobe rod. The utility model has the advantages that the length of the refrigerating area on the cryoprobe rod is adjustable so that the refrigerating effect can be more convenient and effective, and the utility model is beneficial to treatment.
Description
This utility model relates to a kind of medical apparatus and instruments, relates to a kind of adjustable needle insertion formula lesion cryoprobe that is used for the treatment of diseases such as pulmonary carcinoma, hepatocarcinoma specifically, and this cryoprobe can be opened under the operation such as abdomen and use opening breast, also can use under thoracoscope or peritoneoscope.
Hospital's puncture type lesion cryoprobe commonly used mostly is the needle-like cryoprobe at present, the independent Use Limitation fruit of this needle-like cryoprobe often can not reach the treatment requirement, for reaching the refrigerating effect that exceeds the time limit, adopt the bit manipulation of wound more than many in clinical, thereby increased patient's misery, also be unfavorable for the healing of wound.
The purpose of this utility model just is to provide that a kind of refrigerating effect is even more ideal, later stage rehabilitation adjustable needle insertion formula lesion cryoprobe faster.
The purpose of this utility model can realize by following measure:
This utility model comprises that front end is the hollow frozen probe rod of sharp cone distal, the front portion of frozen probe rod is a cooling space, the front portion that is positioned at the hand-held loop bar at frozen probe rod is equipped with the adjusting loop bar of length less than frozen probe rod length, be mounted with the hand-held loop bar at the rear portion of frozen probe rod, offer refrigerant gas input port and outlet in the rear end of frozen probe rod, in the frozen probe rod cavity, be mounted with the refrigerant gas input pipe that is communicated with the refrigerant gas input port.
This utility model is positioned at the hand-held loop bar on frozen probe rod front portion is provided with screw thread, regulates loop bar and frozen probe rod for being threaded certain other suitable connected mode that also can adopt.The front end of refrigerant gas input pipe extends to frozen probe rod cavity leading section.The front end of frozen probe rod also can be designed to other suitable sharp shape, so that thrust the sufferer tissue, the length of its hand-held loop bar should be suitable, and it is for regulating the scope of freeze space that the hand-held loop bar is set, can regulate the refrigerated scope of paracentesis depth and lesion within the specific limits, be beneficial to treatment.
Because this utility model adopts the most advanced and sophisticated hollow frozen probe rod of band, the refrigerated scope of paracentesis depth and lesion can be regulated within the specific limits for the cooling space of the special use of being made by red copper in the front portion of frozen probe rod, makes cooling effect more effective, helps treatment.
Accompanying drawing is this utility model cutaway view.
This utility model is done explanation in further detail below in conjunction with drawings and Examples:
As shown in the figure: this utility model comprises that front end is the hollow frozen probe rod 1 of sharp cone distal, the front portion of frozen probe rod 1 is a cooling space, the front portion that is positioned at hand-held loop bar 3 at frozen probe rod 1 is equipped with the adjusting loop bar 2 of length less than frozen probe rod length, be mounted with hand-held loop bar 3 at the rear portion of frozen probe rod 1, offer refrigerant gas input port 4 and outlet 5 in the rear end of frozen probe rod 1, in frozen probe rod 1 cavity, be mounted with the refrigerant gas input pipe that is communicated with refrigerant gas input port 4.The front portion that is positioned at hand-held loop bar 3 on frozen probe rod 1 is provided with screw thread, regulates loop bar 2 and frozen probe rod 1 for being threaded.The front end of refrigerant gas input pipe extends to frozen probe rod 1 cavity leading section.
Use principle of the present utility model is as follows: during treatment frozen probe rod 1 is inserted diseased region, and the length of regulating the position change freeze space of loop bar 2 as required by adjusting, frozen probe rod 1 forward freeze space is among the sufferer organ, sufferer organ scope should be slightly stretched out at the two ends of freeze space, feed liquid nitrogen then, enough refrigerating capacitys are provided, are enough to destroy lesion tissue.
