Abstract
The utility model discloses a surgical contra-angle handpiece capable of cooling a back part bearing through internal water circulation. The surgical contra-angle handpiece is provided with an elbow-shaped piece, wherein jackets are arranged on the two sides of the elbow-shaped piece; a transmission shaft component is arranged in the elbow-shaped piece; a connecting sleeve is arranged between each jacket and the transmission shaft component; the connecting sleeves are fixed with the transmission shaft component through bearing pedestals; inner grooves are respectively formed in the connecting sleeves; a water inlet and a water return opening are respectively formed in each inner groove; the outer sides of all the inner grooves are drilled through; ring-shaped grooves are formed in the fixed ends of the connecting sleeves and the bearing pedestals; the ring-shaped grooves and the through holes of the inner grooves below the ring-shaped grooves are drilled through through the upper parts of the connecting sleeves, so that cooling water channels are formed in the butting parts of the bearing pedestals and the connecting sleeves; process mouth parts, on the connecting sleeves, of the ring-shaped grooves are sealed by pressing in steel balls, and the ring-shaped grooves are sealed by using O-shaped rings on the bearing pedestals. The surgical contra-angle handpiece disclosed by the utility model has the advantages as follows: the internal temperature of the surgical contra-angle handpiece, especially the temperature of the bearing can be reduced effectively during working, therefore, the service life of the surgical contra-angle handpiece is prolonged, and security and reliability of the surgical contra-angle handpiece can be improved.
Description
Technical field
This utility model relates to surgery acute angle handpiece, particularly a kind of surgery acute angle handpiece of internal water circulating cooling rear bearings.
Background technology
It is inevitable that surgery acute angle handpiece produces heat in the time of running work, but serious heating can cause certain negative effect, and especially acute angle handpiece belongs to handgrip part, and excessive heating affects doctor's operation; And can aggravate the wearing and tearing of acute angle handpiece rotating part; In addition, if do not use when shell acute angle handpiece general work coolingly, inner rotary part is because of high-speed rotary then produce heat like this, the engagement of gear train also can produce heat, bearing is sharply wearing and tearing therefore, can make like this life-span of surgery acute angle handpiece greatly reduce, and reliability cannot ensure.Therefore, be necessary to research and develop and a kind ofly can effectively solve the heat problem that surgery acute angle handpiece produces in the time of running work.
Utility model content
The purpose of this utility model is to produce the impact that heat causes acute angle handpiece for original surgery acute angle handpiece because of when work, a kind of surgery acute angle handpiece of internal water circulating cooling rear bearings is provided, and can effectively solve practical application time, surgery acute angle handpiece causes the wearing and tearing of head rotating part and bearing portions and has influence on doctor's operational issue because generating heat.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of surgery acute angle handpiece of internal water circulating cooling rear bearings, there is an elbow part, be provided with overcoat in these elbow part both sides, elbow part inside arranges transmission shaft component, it is characterized in that: between overcoat and transmission shaft component, be provided with adapter sleeve, described adapter sleeve and transmission shaft component are fixed by bearing block, on described adapter sleeve is axial, have respectively internal channel.
Preferably, described adapter sleeve and described bearing block stiff end offer ring-shaped groove, and described ring-shaped groove is along the circumferential conducting of bearing block, and adapter sleeve top drills through ring-shaped groove and internal channel through hole, form cooling water channel.
Preferably, in described internal channel, be provided with water inlet and water return outlet
Preferably, described adapter sleeve is used the sealing of O type circle with bearing block stiff end to contacting.
Preferably, described internal channel and ring-shaped groove technique oral area steel ball indentation sealing.
This utility model produces this root that affects that heat causes acute angle handpiece for conventional surgical acute angle handpiece because of when work, an internal water circulating cooling part is set dexterously, cooling water enters from water inlet, after ring-shaped groove, water return outlet by internal channel flows out again, form one inner cooling water circulation; Make it can to rotate freely by 360 degree after the docking of supporting polisher, internal water circulation can not be affected, the object that still can normally work.
Brief description of the drawings
