Disposable speculum having lateral stabilizing mechanism
First Claim
1. A speculum comprising:
- an upper member comprising an upper blade which has a distal end and a proximal end;
a lower member comprising;
a lower blade having a distal end and a proximal end and having a right side and a left side when viewed from the proximal end of the lower blade, the lower blade comprising a first support structure positioned on a first side of the right and left sides of the proximal end of the lower blade, anda handle portion connected to the proximal end of the lower blade and defining a vertical track on a second side of the right and left sides of the proximal end of said lower blade, said second side being opposite said first side, such that the lower blade and the handle portion are each asymmetrical when viewed from the proximal end of the lower blade; and
a linear support member having a proximal end pivotally connected to the proximal end of the upper blade, a distal end, and an elongated body between the proximal end and the distal end of the linear support member, the linear support member comprising a first slot disposed on said first side thereon so as to correspond to the first support structure, wherein the first slot comprises a base and two opposite sidewalls, a lateral direction across the proximal end and the distal end of the lower blade substantially traverses the opposite sidewalls, and the first support structure rides within the first slot and is restrained between the opposite sidewalls of the first slot,wherein the elongated body of the linear support member slidably engages the vertical track of the handle portion.

Abstract
A speculum includes upper and lower members and a linear support member. The upper member includes an upper blade. The lower member includes a lower blade and a handle portion. The lower blade includes a support structure at a proximal end thereof which extends vertically on the right or left side of the lower blade, and a handle portion extending downwardly from the lower blade and defining a vertical track. The linear support member has a proximal end pivotally connected to the upper blade, a distal end, and an elongated body between the proximal and distal ends. The elongated body slidably engages the vertical track of the handle portion. The linear support member is formed with a hidden slot which slidably receives the support structure of the lower blade.

2. A speculum comprising:
-
an upper member comprising an upper blade which has a distal end and a proximal end; a lower member comprising; a lower blade having a distal end and a proximal end and having a right side and a left side when viewed from the proximal end of the lower blade, the lower blade comprising a first support structure positioned on a first side of the right and left sides of the proximal end of the lower blade, and a handle portion connected to the proximal end of the lower blade and defining a vertical track on a second side of the right and left sides of the proximal end of said lower blade, said second side being opposite said first side, such that the lower blade and the handle portion are each asymmetrical when viewed from the proximal end of the lower blade; a linear support member having a proximal end pivotally connected to the proximal end of the upper blade, a distal end, and an elongated body between the proximal end and the distal end of the linear support member, the linear support member comprising a first slot disposed on said first side thereon so as to correspond to the first support structure, wherein the first slot comprises a base and two opposite sidewalls, a lateral direction across the proximal end and the distal end of the lower blade substantially traverses the opposite sidewalls, and the first support structure rides within the first slot and is restrained between the opposite sidewalls of the first slot, wherein the elongated body of the linear support member slidably engages the vertical track of the handle portion; a light source; and a light guide disposed on the lower member for transferring light from the light source to a working space between the upper blade and the lower blade, wherein the light guide has a groove therein, and the groove has an open side closed by the lower member to form a smoke vacuum channel. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
