Monitoring and other advantages, can provide important guiding for the diagnosis and treatment of patient's state of an illness.
Existing insertion type probe is broadly divided into two kinds, and a kind of is the probe using optical fiber sensing technology, and another is to adopt
With the probe of micro-electronic sensor technology.Wherein, micro-electronic sensor probe is by laying microelectronics pressure, temperature on intervention probe
Spend sensing element to realize measurement, be gradually widely used in clinic.
Micro-electronic sensor probe is made up of intervention probe and sensing element assembling, due to intervention probe and sensing element volume
It is small, during practical set and use, it is easy to cause the positioning of sensing element loosely and displacement.Therefore, probe makes
The position of constantly adjustment sensing element is usually needed in assembling process, the technology difficulty for making assembling is very high, inefficiency, and
Make in assembling process, it is bad that the displacement of sensing element may result in end properties of popping one's head in.
Chinese patent 201510630654.7 discloses a kind of implanted monitoring probe, and its near middle of popping one's head in is provided with groove
For laying pressure sensor, front end is equipped with temperature-sensing element, but the probe is not used for the dress of fixed sensing element
With position limiting structure, sensing element is only realized by the holding power of wire and positioned, can not strong fix sensing element, in follow-up work
Sensing element is easily shifted in skill；Further, since lack the structure of strong fix, must in practical set operating process
It must ensure that disposable be directed at sensing element is put just, otherwise just need to adjust lead and sensing element repeatedly in atomic thin space
Position, this multiple adjustment repeatedly easily bends lead, moreover, the active force being attached to repeatedly on sensing element can
Sensing element and wire break, and the failure of sensing element in itself can be caused even to rupture, too high production cost is caused
With relatively low production efficiency.

Cavity front end face is surveyed, positioning front of the slot both sides set transition arc, and logical wear in locating slot rear end is connected with the endoporus at assembly connection end
Logical, the depth of the locating slot is more than the thickness of the first sensing element.
By such scheme, described intervention probe body is cylinder, described sphere import termination be semicircle sphere or
Small semicircle sphere.
By such scheme, described Blind locating holes are axially opened in below detection body leading portion along intervention probe body, hole
Mouth is connected with the endoporus at assembly connection end, and bottom hole extends to the front edge of intervention probe body.
By such scheme, offer through hole in the bottom of locating slot and be connected with Blind locating holes.
By such scheme, described intervention probe body and sphere importing termination material are the rigidity such as stainless steel, titanium
Metal or high polymer material.
The beneficial effects of the present invention are：1st, structure setting rationally, is easy to assembling, positioning stablity.Insertion type is popped one's head in reality
In the assembly technology of border, sensing element is fixed in detection cavity, miniaturization and high-accuracy property due to probe, in operating process
In, often due to the movement for lacking the structure for limiting sensing element position and causing sensing element, the present invention set locating slot and
Blind locating holes structure, can preferably with sensing element phase configuration, it is simple and effective that positioning action is played to sensing element, it is to avoid dress
The random movement and positioning that sensing element occurs during matching somebody with somebody are forbidden the failure of the wire kink and sensing element caused very
To rupture.2nd, the present invention detection cavity bottom set locating slot, the underface of locating slot and with probe body diameter parallel
Place is provided with a Blind locating holes, for laying second of sensing element, then the survey of multi-parameter can be realized in same probe
Amount.3rd, the present invention sets technology groove on the front end at assembly connection end with detecting the joining place of cavity, is ensureing probe function
On the premise of structure, processing technology is simplified, the requirement to process tool is reduced and then reduces production cost.
